Measuring behind- low FHR

Shayla

I had an ultrasound done at 7w 3d and the baby only measured 6w 0d. They also told me the heart rate was pretty low at 87BPM. When taking labs they said my HCG is increasing (about doubling) but show a pregnancy in the 7/8 week range. I do typically have high HCG levels though so this doesn’t worry me.

I have a follow up ultrasound tomorrow but, do I prepare for the worst?
