I had a follow up u/s today, 12 days after my ER visit with the pain in my side. Baby is in the uterus (in case you didn't read the other post) but had measured 5w6d 12 days ago. A follow up u/s was scheduled for today to see the hb and check my cyst (causing the pain). Today we saw a hb at 124bpm but I am only measuring 6w5d. So 6 days of baby growth in 12 actual days. I was VERY concerned about this (especially since I lost a pregnancy in Jan at 14w when baby didn't grow, stayed between 5-6 weeks size and hb was around 90bpm). The u/s technician told me that the measurements are very accurate in the 1st trimester. The nurse I spoke with afterwards thought it wasn't a big deal. Based on when I Oed I think I am 8w along. Then the nurse suggested I remain "cautiously optimistic" and scheduled a followup u/s next Monday to check on the baby's growth. I booked the appt but think I will cancel and book a normal 1st prenatal visit and just call if anything happens (bleeding, pain, etc). I do have some photos of the little one. I read a scientific study that if the hb between 6.3 and 7w is over 120bpm the chances of m/c are 9.1%. I am afraid I will just freak out if I have another u/s and I just can't handle it. Is it too much to ask for a normal pregnancy and healthy baby? I hope not. Anyway, thanks for reading and I appreciate the opportunity to vent.
