Minnie: I'm wishing so hard for you that the news will be good but I understand why you are scared to hope when the doctors aren't giving you 100% reassurance. I've been told that in general there is a range for heartrate and size that they expect to see at certain points in the first trimester and they get worried if you are measuring more than a few days behind. (I think size and HR tells them more than HCG levels?) But even with these there might be some variation? If only it wasn't such a terrible waiting game.... I'll be thinking of you and hoping for good news. Could you get a scan done after one week (instead of waiting two) or does the doctor think it won't give you enough information?
