I'm so, so sorry. Is it possible you aren't as far along as you/they think? So many hugs to you, friend.
Not really. My beta was 730 eight days ago. So she should have been able to see a lot more if it had continued doubling. She said if my number today was under 10k then there's still a chance, but if it's over that then it's probably not good based on what she could see on the ultrasound.
So with my second pregnancy we didn't see anything (like NOTHING) on the u/s at 7 weeks. My beta numbers were definitely high enough that we should have seen something - at least a sac and technically a heartbeat. So they had me do more bloodwork and it kept going up. At 8 weeks and a few days we finally saw him. With my first, we didn't see him until 7 weeks - again with the numbers I had we "should" have seen something and my ob prepared me for the worst. They (the u/s tech and my Ob) think my uterus became more tilted as I got older and that's why he was harder to see the second time.
I am so sorry you are dealing with this. I hope you come back here soon with a better update.
