Hi, Im coming up on 7 weeks pregnant 32 days after embryo transfer through IVF and was told 2 weeks ago i had miscarried as i had started bleeding and my hormone level had dropped from 481 on 03/05/11 to 230 on 05/05/11 the clinic continued to check my levels and i was told on 09/05/11 that the levels had risen again to 1051 and i got an internal scan on the 10/05 they located the sack in the womb and they said everything looked well and were happy with what they could see at that point and brought me back today 12/05 for another scan again i was told everything looked good that the baby had doubled is size from last week and that they were very happy with everything but 2 hours after the scan i started bleeding very heavily i contacted my clinic and all they have told me to do is rest until tomorrow and see how things go and if i was still concerned to call them back but im very worried that iam miscarrying is this not something that would or could have been picked up on my scan today?
