I hope your sonogram goes well tomorrow. My last pregnancy ended in a miscarriage, so I think that is why they had my hcg levels checked. I have a sonogram scheduled for 5 days from now. The waiting and worrying is driving me crazy, but I have no choice but to just wait and hope.
My HCG numbers at 5 week 4 days were 14,156.. They definitely vary for people so it is hard to say if they are too high..
They will slow down in doubling once they get high... It can take up to 96 hours or more to double after they are that high so wait and see... Try not to stress as long as they are going up for now.
I don't know sweetie but I was about to post a similar question! My levels @ 5w4d were 24,000+ (which I thought was great!) but then @ 6 weeks they were only 32,000. I was very diappointed but the nurse told me that sometimes, once they get "that high", they don't double as quickly.
I would stay positive if I were you. Why did they do early hcg tests, anyway? Do you have a history of m/c? If so, maybe you can get an early sono. I have one scheduled fro tomorrow. Good luck!
