10w3d today and the Dr. couldn't find the HB on his doppler. It finds at the earliest at 10 weeks. Now I wouldn't be nervous if we were able to find it ourselves or if we had never heard it. But we found it last thursday at 9w3d on our doppler and haven't been able to find it since.
I have another Dr. appointment next Thursday to try find it again and if they can't, they'll send me for another u/s to double check.
KMFX. I'm trying to stay calm.
