Those who had low/slow betas, what happened at your first ultrasound?

[Babazoozoo]

My betas started low (59 - IVF pregnancy) but doubled appropriately. Because it started so low I expected to see something off by my first ultrasound and I was right. The baby is measuring 6+1 instead of 6+4 and the gestational sack is very small. Heartbeat of 122 though.

Obviously this is alarming and I’m preparing for the worst, but part of me also wonders - isn’t it expected to have things be a little behind if your hCG started on the lower end since the embryo started off “behind” to begin with? I’m hoping things will catch up by 7, 8, and 9 weeks, etc. but wanted to ask if I’m the minority on having a bad first ultrasound with low starting betas.

Thanks!

This forum sucks no one ever replies to anythinggggg :/

I'm sorry you didn't get a reply - part of this I think is because betas aren't the norm in the UK, it's only a subset of the forum who would be able to answer.

Have you tried the Reddit IVF forum? It's not something I would usually recommend, but because it's mainly American, there will be a lot more women who have been in your position and can offer insight.

@Babazoozoo was it a frozen transfer? Over 50 is fine for FET. Mine was 60 and my child is now 4 years old. Also the measurements at this stage are so small that it is easy to make an error, so long as it is less than a week difference I would still be hopeful at this stage.

congrats on your pregnancy!

Would you mind me asking why you are preparing for the worst? I think the dates can be slightly off as the measurements are so tiny and a difference in a millimetre can be huge. Was your clinic concerned with the results?
