Ok so I had a positive pregnancy test on 12/16 but started bleeding went to er and hcg was at 7, on 12/18 @14, 12/26 @73, and then on 12/31 down to 64. I was told that I was going to miscarry but I have still had no bleeding and still get a positive test but with a darker line, is it possible that it could be a viable pregnancy or should I expect the worst? Or maybe get my levels tested again?
