I have a horrible feeling my sister has been told something which isn't true. She called me earlier to say that the doctor has siad the hCG level has risen from 24 last Thursday to 64 on Tuesday. That's a rise of 40 in 5 days but it should be doubling every 2 - 3 days and to my mind it just doesn't work out. She has been told to go to hospital for a scan. Her dates put her at about 6 weeks so maybe they will see something, and I really hope they do, but I am wondering if her doctor really knows what he is talking about.
