I had a dating US today, and the baby measured smaller than expected. Before anyone says I must have ovulated later than I thought...I will share the dates with you that are relevant. The date of my positive pregnancy test compared with the measurements...PLUS the only day of sex being so early make me think that this pregnancy isn't growing correctly and I should prepare for the worst.
April 24-LMP (CD1)
May 4th-got my baby-making freak on with DH (it was a lonely month for DH, poor guy)
May 22nd-got positive test with afternoon urine on FRER
May 23rd-positive test with digital test and FMU
June 13-sonogram shows a fetal pole and yolk sack. No measurable heartbeat (though the doc said he could see a possible flicker, I saw nothing.) They say I am measuring at 6 weeks.
So...if I'm 6 weeks today...my positive pregnancy test would have been at 2 weeks 6 days. Which obviously wasn't the case, but...with a positive test over 3 weeks ago, I don't see how I could just now be 6 weeks. And I definitely don't see how I could be 6 weeks with the sex being that long ago.
So...should I prepare for the worst? My follow up isn't until the 24th. That is a world of time away. I don't want to have false hope for 11 days. I really can't wrap my head around this being possible...am I missing something?

Re: Imminent miscarriage...or freak of science?
They won't do repeat Betas because I'm traveling for business next week, across the country. My biggest fear is that I will be there, with no doctor or support system at all, and start to miscarry.
My doctor told me that I shouldn't worry until my next visit, 11 days away. Which is sort-of impossible to do. He said for a six week pregnancy, it looked normal. I said, but what if it was a 7-8 week pregnancy that looked like that? And he said, well, no, but we have to assume it's good for now.' I know was trying to make me feel better, but I don't think anything but my follow up ultrasound being good will make me rest easy.
The have LabCorp and Quest diagnostics all over the country. All you do is bring in the script and they fax to your doc. If her or her doc doesn't want to do them, that's fine. It was a suggestion based on what *I* personally would do because I would not be able to wait. That's me.
Looks like you should give that a scan yourself as it just reiterated what I already said. As hcg increases so does the doubling time. However there is still a normal range. It's not rocket science.
It's a range. It's a guide. If they double faster then that I'm pretty sure any one with half a brain would know that is positive. If it's been several days and it's barely moved, stagnated or in many unfortunate cases fallen miscarriage it is very useful information. The end.
I am guessing the doctor would have ordered a repeat sonogram sooner, but for the fact I'm traveling. He was really nice and told me that the fact he saw a fetal pole and yolk sack and that the gestational sack was rounded and not irregular borders was a good sign. He said that there have been times where nothing makes sense, as far as timing/dates goes and there was still a healthy baby at the end. So, that, along with my current morning sickness, is what I am holding on to.
I'm hoping that the frantic pace of my business trip keeps me distracted, and that I have good news in 10 days. Thanks for the input. I am hoping for the best but aware that only time will tell the outcome.
I hope everything is fine!

They haven't run betas, at least not the kind that can show doubling because they were a week apart. The biggest issue here is that I had a positive test at what would have been '2 weeks, 6 days pregnant' (assuming I am actually 6 weeks pregnant as the ultrasound indicated.). We all know that's just...not right.

The betas they drew, both last week and this week were not specifically to check for doubling. It was just part of the overall picture of what they are looking at.
And maybe I'm extra sensitive, but hope I get the outcome I wish for? Is there any desirable outcome besides a healthy baby? Since the alternative is a miscarriage...and I would want that instead? I was with you and appreciating your thoughts but this statement really rubbed me the wrong way. I'm hoping I am just being cranky and over sensitive and misinterpreted a nice sentiment.
Thank you for taking the time to clarify. I hope you have a sticky and healthy baby.
only a guestimate when you're that early along. I'm now 9 weeks along & everything's going well so far. I know it's difficult, but try not to overanalyse. You'll only drive yourself crazy. I'm sure it'll be fine
If you actually read my post, you would see I had a previous ectopic, which is why I went for an early scan.... All I did, was tell her that it is possible to get a positive at 3 weeks and to try and relax. Why is everyone so cranky on this forum??? On every single post I read, I just see people (without medical degrees) questioning their doctors & correcting each other using their years of expertise attained from Google. Bye!!! I don't need this. Hope it turns out well for you OP.
