Please help!!!!

Hey everyone. I've seen post similar to mine and this seems to be only place I feel comfortable asking nobody knows me.

Okay here we go.

On 3/9/16 I had sex with a guy who says he didn't no ejaculate inside me. That was the only time I had sex with anyone other than my boyfriend and I'm not sure how many times and what dates the rest of March my boyfriend and I had sex but we did multiple times. I was in the hospital on 3/12/16 and they didn't a urine pregnancy test it was negative then at the doctor they did one on 3/25/16 and it was negative my first positive test was on 4/7/16 that was from a dr.office vist where the urine sample is sent to a lab. My ob dr. Told me date most likely date of conception was 3/25/16. My EDD is 12/16/16. Every conception calculator I've done had not given my a conception date earlier than 3/20/16. On 5/8/16 My ultrasound said GA was 11w6d. Can someone help me out? Guess I'm looking for reassurance if everything I've been told his true about My conception date. I also had gone off the depo shot in Jan.and I was breastfeeding at the time of conception. I also dont understand the count back two weeks from Ga like do you do that when you do a conception calulator too? Please help!thank you

Did you get your period after the guy you had sex with on the 9th?

Well that's not fair! Getting some legit help and answered to big a concern and then not letting the person who helped know how it all went!

It is perhaps not polite, but it is a common phenomenon in an anxiety-driven community like DNA/Paternity.  When someone is anxious they think only about their issue, and ask and ask and ask, they even move on from one forum to the next to ask new people.  Then when their definite answer has come, they forget about how worried they were (and the efforts of everyone to help them), and just move on as though they never made a fuss.  It's a pleasure to hear back from the few who do write after the baby is born and everything is settled.  It would also be interesting to get the feedback -- how many times all the figuring turned out to be correct.  I've never had anyone write me back and tell me we were wrong when we figured out their dates in this community, but that is probably because when things are close, we say so, and only when they are super clear do we give a firm answer.

I assume you are asking if it rules out the 9th, not if it proves the 25th.  A negative on a urine-based pregnancy test on April 1 really doesn't "back up" getting pregnant on March 25, all it can do is rule out any sex that is at least 28 days earlier than the test.  This is because it is a urine-based test.  Urine can be concentrated or dilute, (if this was done in the daytime when you had already drunk liquids, you could have even been pregnant and it might still register negative). And doctor's-office pregnancy tests are not the most sensitive -- even the Dollar Store tests register positive with lower amounts of hCG than the ones doctors use.  Also, sperm can live up to 5 or 6 days in your system (nobody is sure what the top limit is, but most research says 6 days would be the longest for the sperm to still be mighty enough to penetrate the egg) and it does take a couple of weeks for the egg to implant and for the hCG to rise to a high enough level to be tested.    

If you had an hCG blood test and was negative on April 1, I'd say, that rules out getting pregnant from sex on the 9th (and any time that the sperm could have lived for from sex on the 9th).  A urine-based test on the 1st might suggest and does seem to help back up the notion you didn't get pregnant from the sex on the 9th but I would not use that as your sole evidence.  Fortunately, it isn't your sole evidence.  :)

Now please stop brooding and worrying trying to find more evidence, all you will do is stew yourself to death.  Assume the baby didn't come from the sex on the 9th, because your doctor told you it didn't, and you didn't even need people on the Internet to tell you so, you should believe your doctor.  Plan to get a quiet DNA test when the baby comes just so you will confirm what the evidence says, and then you will never have to worry about it again.

If you have any friends who have had ultrasounds done and kept the photos, you could ask them how much their baby wound up looking like the picture in utero.  My son did in some ways and didn't in other ways.

Okay so looking at summary of vist and only thing I could find that is different is before the ultrasound I meet with one off the same offices mid wives and she has 7 weeks In my chart..I know like an hour after I saw her I had the ultrasound done then was given the 11w6d and e.d.d 12/16

Everything counts back to conception around March 25 except the first ultrasound.  In your shoes I'd write the first one off as an error.

Okay so the weeks of 11w6d is on the ultrasound along with the date of 5/3. All done at the same Dr. Office that told me about the lmp of 3/11 and probable conception date of 3/25. The E.D.D has not changed at all thru this pregnancy . I was a bit confused as well. Could be that the baby is just bigger and measured size of 11 week baby? I don't know anything about all this stuff. Looking at other ultrasounds right now on 7/21/16 Ga is 18w6d on 9/29 Ga is 28w6d and 10/31 Ga is 33w3d. If that helps at all. I was thinking if I did have a conception date the week of Feb 24 by March 25th that HCG would came back positive in the test. My worries are that it's all messed up and I did around March 9th obviously.I'm going to log on my records see if I can find anything else I'll post another comment with what I find

This is actually the reason I never use "weeks" counts to try to date a pregnancy once someone gets a due date from a reliable ultrasound.  They are always loosey-goosey for various reasons.

You're saying you were 11 weeks 6 days on May 3.  But a count of11w6 on May 3 is four weeks too much, given everything else the doctor told you.  If the doctor told you that your period (absent the effect of depo and the breastfeeding) would have come on March 11, you would have been more like 7 weeks 4 days on May 3.  How reliable was the ultrasound?  Do you have those figures from a medical report that you actually have in your hand, or is this just what you remember someone saying?

If you were 11w6d on May 3, you would have conceived on February 23,  But you say that your doctor told you that your period would have come on March 11, and that you conceived around March 25.  You had negative pregnancy tests until April.  (You certainly wouldn't have had negative pregnancy tests until April if you had conceived in February.)  Did you get the 11+ weeks count from the same doctor that told you that you are due on December 16 and that you conceived on May 25?  

It's not like any of this implicates the sex you are worried about (even if it were correct and everything else, the due date and pregnancy tests, were wrong), because February 23 is way too early for Mr. March 9.  But it doesn't add up to anything else the doctor said.
I'm just reading all these and I'm dying to figure out what my results are, I too have lost sleep over this confusin and the "what if questions" can not wait to see your outcome and can not wait for annies reply on my post :(

That makes alot of sense thanks for explaining! I'm not sure where he got the 3/11 from I was honeslty a bit confused from that but he did say most likely conception date was 3/25 as well. My E.D.D has not changed and all dates that I've stated are correct!
Thanks again Annie
Also what did you mean in yoir,second to last paragraph? About the oveturn of ultrasound on May 8th. Can you explain more in general about that paragraph?

Mum, all I meant was, go with the estimated due date and the other clues.  They outweigh the notion that on May 8 you were 11 weeks 6 days.  The doctor obviously was using the estimated due date as correct if he told you that you would have had a period on 3/11 (if you hadn't been breastfeeding and coming off Depo).  Go with what the doctor said about your estimated due date based on the ultrasound.  It is backed up by your pregnancy tests.

I'm sure you didn't get pregnant from the guy on March 9.  The earliest you could have gotten pregnant from what your ultrasound said in your 11th week is March 18 or so.

Thank you so much Annie! I've seen everyone on this site in this section comes to you and so I was hoping you would comment for me. That makes me feel alot better!
But if GA on 5/8/16 was 11w6d., so that puts conception on February 29? But why EDD is 12/16/2016 then..
Sunshine, doctors count pregnancy as being 280 days long (40 weeks) even though pregnancy is in fact only 266 days long from conception to birth.  They add the extra 14 days (two weeks) at the front end, to move the beginning of the count back to the (presumed or calculated) first day of the last period.  

They use the period to start the count because in grandma's day, that was the only signal they had, they didn't have ultrasounds.  They don't think a woman is pregnant when her period begins, she's having a period!  But it is a big, obvious signal, and ovulation (which happens around two weeks later if a woman's cycles are regular) is hidden and unknown.  

All medical counts of pregnancy calibrate the count of pregnancy to the first day of the last period.  All textbooks, all ultrasounds, all nurses and doctors.  It is confusing; people at their doctor's offices get thrown for a loop all the time when they are told "weeks pregnant."  It can be especially tough when the guy has not been with his wife two weeks before conception, and he thinks it means she was cheating.

The poster had an ultrasound relatively early in her pregnancy, which helps because later ultrasounds can be inaccurate for purposes of dating pregnancies (the margin for error gets wider as the pregnancy goes along, to the point that by the 40th week, it can be three weeks off).  Her ultrasound looked at and measured her actual baby and gave her the due date of December 16.

The length of a full-term pregnancy from conception to birth is 266 days, (from conception to presumed first day of last period is 280 days).   Counting back 266 days from December 16 gives an estimated conception date of March 25.

There is a possible margin for error by the 11th week when using an ultrasound for dating purposes of +/- about a week.  From her ultrasound (backed up by her pregnancy tests), I don't see her getting pregnant any earlier than March 18.  

The doctor's count of "11 weeks 6 days" would count her back to March 14 for conception at the very earliest, not February 29.  But the doctor also said he or she thought her period would have begun March 11, obviously the doctor was not saying she conceived on March 14 if he or she was saying her period would have begun March 11.  It's hard to say what the doctor meant with that week count when getting the information secondhand like this and after all this tie. We often see the "weeks" number being wrong in posts on this site, either because the doctor was being casual when speaking to the person, or because the person remembered it wrong, or because the person got it on a different date than they remember, or because they got their estimated due date later and there had been some change in the due date in the meantime.  This is why I asked the poster specifically if the doctor said the due date on May 8.

In this case, everything else lines up with the e.d.d. as computed by the ultrasound.  Saying "11 weeks 6 days" on May 8 is not enough to overturn an ultrasound-generated due date in the first trimester.  The e.d.d. is also backed up by the dates of the negative pregnancy tests.

The o.p. said she was given the due date of December 16 on May 8, from an ultrasound, relatively early in her pregnancy.  That's what I was going with.

How early were you given your estimated due date?  Was it from the ultrasound on May 8?
