Just wondering whether anyone else has had a high HGCb after having methatrexate a few Months earlier? I had ectopic in May and I am 13 weeks pregnant now and been given a 1 in 5 Chance of downs. NT 2.3, pappa 0.6 but HGCb 4.2. Had harmony bloods done today - waiting for result. I have a uterine fibroid which one scanner said was large - another said nothing to worry about?
