Gestational sac not measuring with estimated weeks....

Hi all....right now I am very confused and upset. Just need a few opinions (good or bad).I found out I was pregnant by a home pregnancy test 2 weeks ago. Last week, I went to the doctor where he also confirmed it. He did the exam and said everything looked good and that I was 7 weeks. I went for my first trimester ultrasound and from there on it has been an emotional rollercoaster. When the tech did the ultrasound, she said that the gestational sac was only measuring 5 weeks and not 7 like it should. She called my doctor and he said he wouldn't know much until I had some blood work done. So, he sent me to the lab to have it drawn to measure my HCG levels and progesterone levels. And I go back Friday for a second set to be drawn so he can compare. He said I might really be 7 1/2 weeks pregnant and the baby stopped growing at 5 and is gone or some other things that I didn't hear because I was still in shock and somehow tuned him out. I feel pregnant. No cramping or bleeding....don't know what to think. My LMP was definetly Aug 26. Anyone have any ideas or suggestions...anything is appreciated. Thank you.

you could have ovulated late and so LMP would not be an accurate due date and age for the baby. 5 weeks all you can see is a sac thats it. as long as your progesterone levels are good and hCG is rising there is a awsome chance that you ovulated later than you thought and that is the reason for confusion. i ovulate on CD 21 so going by LMP won't work for me either. it happens and untill they confirm your blood results unfortunately there is nothing to do but wait. i had a m/c 2 months ago and felt PG when they called to tell me that my levels had dropped to 7 and it was the next day that i got AF. it was awful emotionally and i so hope you don't have to go through that. many woman are given a wrong due date and gestational age because the docs go by LMP....lets hope they made this mistake with you. you are in my thoughts and prayers.

love and hugs.....kimmie

I would wait and see. Try to positive. I had a friend that was told that she wasn't pregnant either, that her body was faking it and that she would end up having a "fake" miscarriage. They told her this until she was about 3 months. She never believed it. She now has a beautiful 2 year old daughter. Do not let the doctors talk you into having a D&C or taking anything to help it along. Just wait and see if your baby grows. There have been lots of stories I heard from women who went through this very thing and they ended up with healthy babies.

Hang in there - I know its tough/stressful to wait and its hard to keep your mind from going crazy with worry.  Try to stay busy.  Its really possible that you did ovulate late.  Going by the LMP can not always be accurate.  The blood tests will tell the story if the Hcg levels rise.  Sometimes I wish we didn't have all these tests done so early because sometimes it just makes you worry needlessly.  Hang in there, good luck on Friday.  Let us know how it works out.

I can feel for you. I just had my 1st ultrasound yesterday & I should be 7 weeks & 3 days & they couldn't find anything. It was like she kept measuring an empty sac. They told me I either had my dates wrong, which I know I had my LMP 9/2, so I can't be wrong. Or they said it could be a molar pregnancy where there is no baby, just a lcuster of sists. Fortunately my HCG levels so far do not indicate that. I need to have another ultrasound in 2 weeks & bloodwork every other day this week to measure my levels. I have convinced myself there is no baby & I am scared I will start bleeding any day now. Everyone says you should be able to see something by the 6th week at least & I know I have to be past that point. I just can't believe this is happening. I don't want to get my hopes up & in 2 weeks there still be no baby. I hope what I wrote doesn't bring you down, but at least you know your not the only one going thru it right now. I wish you the best of luck & please keep us updated.

I went in for my 8 week ultrasound and found that the sac was measuring small. They said it could go either way. The baby had a good heart beat so we went in for an ultrasound 2 weeks later and the baby was fine. I'm 20 weeks now.

I too had a bad sonogram at 8 weeks. The sac was measuring very small and the sono tech thought I would prob miscarry. I went back in at 13 weeks and everything measured perfectly. I am now 20 weeks too with a baby girl.

Hi everyone! I was just reading some of the postings and wanted to know if anyone could give me any hope? I conceived throug IVF on 10/16 (transfer day). On 10/25 they did my preg test and it came back good at 150....Then today, one week later that wanted to see me for more labs and ultrasound. When they were doing the ultrasound they could not find anything, not even an empty sac! The doctor said I may have miscarried or I have an ectopic. We waited for my new HCG levels today and they came back at a surprising 3300. We were expecting more around 2400. So that was at least good. My estrogen and progesterone were holding steady as well and they want to see me this friday to do another ultrasound.......Has anyone ever heard of such good HCG and blood levels and yet they can't find anything. The doctor is pretty sure it's not ectopic only because my numbers would not of doubled to nicely........Help

I have also undertaken IVF. My implantation date was on 09/27. I went in for my first ultrasound (7W 4D according to the IVF clinic) on 10/31. The technician was able to locate the feotus and gestational sac however she noted that no heartbeat could be found and that the feotus seems to only measure at 6.5 weeks. The IVF doctor advised me that based on these results, my pregnancy is not viable and that he would like for me to schedule a DnC ASAP. No additional ultrasounds were offered and/or bloodwork. I have been in a haze since 10/31 and would really prefer to hold out until other tests confirm those results. I feel pregnant and have had no bleeding/cramping. I do have a 2.5 year old daughter who was conceived naturally and who was by no means a textbook pregnancy. Anyone else had a similar experience.....

Hi Everyone,
I just found this site tonight - after coming home from a horrible experience with my doctor. My husband and I found out 2 weeks ago that we were pregnant. We are approximately 6 weeks along. Yesterday I had some slight bleeding (very little but enough to cause concern) and I contacted my doctor immediately. Her response was "to let mother nature take its course" and that there was "nothing I could do". I was upset by her response considering it was only light bleeding that lasted under 30 minutes and I felt like she had already counted my baby out! Furious I commented and told them so and they were able to "squeeze" me in for an appointment the next day (today). I took matters into my own hands and left work and went to a local clinic to the urgent care and the doctor immediately put me in for an u/s. The technician told me there was a sac and that it appeared I was 5 1/5 weeks along. She told me there was no heartbeat but that considering the number of weeks that is to likely be expected. I left there feeling much better than I had been earlier. Tonight my husband and I went to get the actual results of the u/s and my family doctor said the results were that they could not find a heart beat (and that the sac was empty). Surprised by this outcome (from what the technician had showed me yesterday) my husband and I asked what our options were. She said another u/s in a week or so would give them a better idea but that they would do some blood work to see what my levels were and I get the blood work results tomorrow. I'm praying that my levels are as high as they are supposed to be and that the next u/s will show a heart beat. The hardest part is that my family doctor didn't appear too positive about things? I just have a hard time understanding how they can be so heartless sometimes. I thought I would share my story after reading all of yours. I wish everyone luck with their tests and hope they have a positive outcome. You're all in my prayers. I'm going to be a first time mother and I can't believe how attached I already am.

Wow, the stories I have read sound exactly like mine.  I got pregnant with IUI on October 14th.  I went in yesterday (Nov 15) for my u/s.  The tech said that the sac was measuring 5 weeks although I was at 6 weeks.  She thought she saw a fetus but it was really small (no heartbeat).  I was basically in tears.  The tech did a really bad job communicating everything to me.  The dr is having us come back next Wed (day before Thanksgiving) for another u/s.  If the sac is bigger, and there is a fetus then there is hope.  If not, I will probably have to take some meds to force it out.  I am overcome with complete sadness.  Even though I am still pregnant, I can't stop thinking that my baby died.  Does anyone have any thoughts?  Thank you.

My question is specifically for the people who've had "small gestational sac" issues.  How far behind were the sacs measuring at first?  Was there a heartbeat with the small sac?  Have you had any other issues with your babies since the small sac was resolved?  i.e. kidneys, lungs??  I'm about 8weeks and on Monday (the 14th) measured at 7w4d with a sac that measured 5w4d.  The heartbeat was a strong 162.  I am preparing myself for the worse, but would love to have a bit of hope thrown my way.  I go back for a followup on Monday the 21st.

Thanks so much!

Hello,
I read everyones post and I first of all want to say Good Luck to everyone....

Her is my story..

I had IVF (Tubal Embryo Transfer) 4 weeks ago today was the retreival. We had 4 Embryos transfered into my tubes. On Nov. 3, 14DPO my HCG level was 123 and I am PG. I have been going in for Betas and HCG is going up. Yesterday I went ofr my Frist Ultrasound and they saw 3 sacs and one had a yolk sac in it. the problem is that, the one with the yolksac is measuring 4w and 5 days. The other is 4week and 3 day and the other is 4w and 1 day. I am so confused becasue I would thing that I should be 6 weeks if my period was 2 weeks before the retreival.
This is our second IVF and the first resulted in early miscarrieage at about 4 1/2 weeks. We have been doing many other things, IUI, Clomid and lots of stuff for 3 whole years

Hi,

I too am experiencing small gestational sac. I had an U/S yesterday and the baby's heartbeat was 135 and measured 7 weeks 2 days, but the sac only measured 6 weeks 3 days. The tech was concerned that the baby is either not getting enough fluid or producing enough fliud. My doctor said that we would be more concerned if it was the other way around. 2 hours later I started spotting. I am not sure I am going to have a miscarriage or not at this point. I still feel pregnant and have intermittent cramping but I have had that the entire time I have been pregnant. I have had 8 miscarriages already and this is my 10th pregnancy. I have a 14 year old son that is my world, but want another one so bad....

The doctors put me on bed rest but I just want to know if everything is going to be okay or not. I am supposed to go for another U/S on the 21st. I don't know what to do!

I spotted a little bit yesterday with dull cramps in my back.  The doc's office wanted me to come in today for an ultrasound.  The gestational sac was measuring 4w6d.  You could see the embryo and the heartbeat.  The embryo measured 6w0d.  I am 95% certain of my dates and should be 6 weeks right on.  The doctor told me that they do not know why this happens but that the outcome could go either way, I could miscarry because it indicates that the embryo is not growing correctly or I could go on to have a normal, healthy pregnancy.  I go back for an ultrasound in about two weeks to check on the progress of the growth.

In August I went for my dating scan expecting to be 11-12 weeks pregnant, unfortunately there was no heart beat and the feotus had stopped growing at about 7 weeks, I had had a missed miscarriage apparently. I had to then go for a D&C, this was all extremely upsetting as you can imagine. I am now about 7 weeks pregnant but when I was about 5 weeks I began to bleed, i went to the doctors (a woman)she told me to put my feet up for 4 days and then to come back, by this point the bleeding had tapered off to just a pale showing and not much. I went back and she booked a scan for me. I went for the scan and there was a heart beat, it was difficult to date but it looked like 4-5 weeks. They also found a fairly large cyst on my left ovary (could explain bleeding) and the possibilty that I might have a Bicornuate Uterus! I don't know what is going to happen and I suppose there is an element of chance and nature taking its course but being a bit of a half empty person I tend to expect the worse then I can only be pleasantly suprised. Fingers crossed hey?

Hi Everyone.  I found out that I was pregnant about 3 weeks ago.  I had an US and the doctor told me I was only 5 weeks because it was just showing a black sac and no emrbryo but according to my LMP I should be approx. 7 weeks.  She told me to come back in 10 days for another US.  I had my appointment booked for 10 days later and was mad with worry the whole time but on the day of my appointment they had to cancel because the doctor was needed in surgery, they couldn

Here is my story to hopefully ease some of your minds. I went in when I was 8 weeks. The heartbeat and baby looked good but the sac measured 7 days behind. It looked terribly small compared to my other early sono's(this is my 5th baby).The sono tech thought I would miscarry. I rented a doppler online at 9 weeks and found the heartbeat. I listened to the heartbeat everyday until my 13 week sono and by then the sac measured perfectly. I am now 24 weeks and had a sono a few weeks ago and everything looked good.

The sac needs to be at least 5mm larger than the CRL (crown rump length measurement) Mine was 7.9mm bigger. There was still a 25% chance of miscarriage with my measurements. If the difference is 5mm or smaller then the chance is around 80% of miscarriage. You might want to ask the sono tech what the difference is because that will help you know your chances.

Also, my doctor told me she has seen sacs measure 1-2 weeks behind and turn out fine. She wasn't that concerned, just my sono tech was concerned.

LuckyJaybird, how are you going? I would love to know that you are having a good pregnancy.

I have a similar story after returning home today from my first u/s at 7w. I went through IVF with retreival on 31 Oct and trasfer of two embryos on 3 Nov. By my calculations the sperm and egg created an embryo 5 weeks ago today, but the doctor says it's week 7. I've felt very pregnant and the positive blood results on 16 Nov confirmed it. I've grown so attached to my 'baby' and the thought of being a mother. I've been eating right, drinking plenty of water and looking forward to the birth. Today's results were totally unexpected and I'm feeling crushed! The sonographer said the sac was not showing a 7 week embryo didn't give me much hope of my pregnancy continuing.  She only said the doctor would call me, which he did as I read the other posting on this board. He said it was not likely that the pregnancy would continue and he was sorry. He rejected my inquiry to bloodwork and an u/s to listen for a heartbeat. His only advice was to wait for nature to take it's course and if I felt it was taking too long, i could schedule a DNC. I guess I'll just give it some time and see what happens.

I hope everyone else is doing well - let us know how you're going....

I need some one to talk to. I am 37 years old and this my 7th pregnancy. I have 5 children and I had a m/c at 6 weeks in September. About Nov. 21 I took a home test and it was positive. I went to the doctor and they confirmed at 5 weeks. They did my labs and my HCG was normal but my Progesterone dropped from 12.9 to 9.7. I went in for an u/s today thinking I am about 6w4d and I was told by the tech that I am measuring about4 or 5 weeks. She made me very nervous about having miscarried again. I am sure of my LMP because it was on my anniversary. Now I have to wait for my bloodwork to come back to check my levels and I to wait another week for an u/s. I just went through this 2 months ago having to share my son's 1st birthday with a m/c baby in me. My nerves are a wreck and I am wondering if I even feel pregnant anymore. I am always sure of my dates, so how could they be so far off? What could be wrong. With the last preg. I bled and cramped the whole time; but, this time there is no spotting or cramping. Help me out someone.
