Hi! Based on my LMP I should be 8 weeks but only measured 5 weeks 5 days. Not too worried since there was a heartbeat of 167 at sono and I'm still nursing so ovulation is most likely out of whack. What worries me is I had my HCG levels done a week and a half ago and if I was only 4 weeks they were crazy high.. and there was only one baby in there. At 3 weeks 5 days I was 2877, and at 4 weeks I was 4930. Nurse told me range was normal and whatever I'm looking at online is wrong. Doctor said the same thing. I had bloodwork done again today and will know more tomorrow. Anyone else have HCG levels this high with success and one baby??? Thank you!
