Early pregnancy

Isabel

Hi, so I found out 3 weeks ago that I was pregant . At my first doctors appointment they couldn't find anything but a sac and toke blood to test my hgc levels . My next app was a week later and she said she could only see a sac but still no baby and she toke more blood and told me that my Levels aren't rising . I went today and she found a baby and a heart beat and told me it was a miricale . She did more blood work and my hgc levels still are not rising so she thinks I'm going to miscarry . I have been cramping and bleeding some so I'm really not sure . Anyone have the same problems ?
