HIgh Enough Hcg levels to detect sac on ultrasound- but nothing seen? ANy Explanations?PLEASE HELP!

[mamatokevin]

I had an early ultrasound done- and they didn't really see anything.
I am 4.4 weeks pregnant- however my hcg levels today were around 3,000.  I have read (and a nurse has told me) that they should be able to see a sac at 1600 hcg.

If my hcg level is at least  2,700 to 3,000- shouldn't they have been able to see anything on ultrasound (even with me being 4.4 weeks pregnant?) If not- what other explanations are there other than a possible doomed situation?
Thanks you so much for your help,
Dawn

I hear they don't often see anything until 6 or 6 1/2 weeks, and not always that early.  Schedule another ultrasound in a week or 2, and keep tracking your HCG levels to see if they are rising.  Good Luck!

My HCG levels were really high for where I was at in my pregnancy. At the end of my 5th week it was 30,000, but still nothing could be seen on u/s.  I dont like that they tell us what should be seen based on hcg levels, because those dont tell us how far along we are.  I was able to see a baby and a heart beat at 6.5 weeks, but never saw much else at any of the 4 previous ultrasounds. Dont listen to them about hcg levels, only pay attention to how far along you are, hang in there. I know it almost killed me because I kept getting bad news, then worse news. I wasnt until I went for a second opinion that I saw the baby, otherwise the other doc wanted a d/c, can you imagine??  

You have strong HCG levels which to me and in my case indicated a healthy pregnancy was brewing, wait just a couple weeks and th

That gives me a lot of comfort- I went back yesterday and my numbers were 3918 and still nothing on u/s. This time the doc said that he suspected twins becuase the #'s are so high (and tripling/quadrupling every 48 hours) and twins makes sense. We shall see- I am going back on Wednesday for another u/s- (if my numbers are at least even doubling They would be around 25,000 by then-- however since they have been at least tripling- they may be even higher.

i wouldn't listen to them about that with all of my pregnancies they couldn't see anything `till about7 wks and my hcg levels were well above 2000 infact during this pregnancy at 5 wks my levels were at 25000 and they didn't see anything and then at 7 wks we did

I actually went back to the hospital yesterday and had my hcg drawn again. It was 3918

(Here they are so far:

5/13 hcg10

5/15 hcg 43

5/19 hcg 398

5/21 hcg 1362

5/23 hcg 3918



I actually saw a doc- becuase I have been having lower back pain and the nurse was worried that I might have a bladder infection (but I didn't). Anyway- this doctor said that he wanted to do another ultrasound. Before he did it- he said that my numbers looked like I could be carrying multiples.  I was suprised this time- because that was the explanation that the perinatologist gave me the day before (because they didn't really see anything on the ultrasound).

Anyway- he gave me an ultrasound and pointed out something that looked like a darker "see through" shadow. He said that could be the begining of something right there.

Anyway- I am supposed to go back on Wednesday (May 28).

My question to you is this: What can I expect to see on the ultrasound based on the following criteria:

I should be (39 days since lmp April 19)/ I received a positive ovulation predictor kit on May2 (so I would be 25-26 days since ovulation) and technically 5.4 or 5.5 weeks pregnant on Wednesday.

Additionally, Since my hcg level was 3918 yesterday than (if it just doubled every 48 hours until Wed it would be around 20,000-25,0000. (if it triples than it would be around 90,000 on Wednesday).

What can I expect to see based on these facts?

Thanks,

Dawn
