it sounds like threatened miscarriage unless your dates and ovulation are off. reast over the next week and good luck
I would tend to disagree. If you last period was November 2, then at 4 weeks of pregnancy that would be around December 2. Then 8 weeks of pregnancy would be around January 2. To get closer to today, add about another week of pregnancy, so you are around 9ish weeks of pregnancy - not quite 11 weeks. My early ultrasound said that I was about a week and a half off of when I knew I ovulated (test strips). Some of us ovulate later, and some of us even implant later (that's me!).
So at this point I wouldn't give up hope at all. I think you calculated your dates a bit off, if you are a later ovulater, a late implanter and maybe baby is a slow grower then all these things can add up to a week or so difference. And maybe the ultrasound showed 7 weeks and a few days - there is some more time!
I would take it easy and do as the dr says, but don't give up hope yet. I wouldn't determine threatened miscarriage until some hcg numbers start showing weird stuff!
