So I had a positive pregnancy test and I went to the hospital bc I was cramping and they took a urin sample it was negative then they did a beta test and said my hcg was 19.95 and said I'm literally 6 or 7 days pregnant I'm just confused they did an ultra sound said everything was normal but couldn't see the baby bc its way to early am I having a miscarriage they want me to come back in a couple of days to see if my hcg levels rise so I took another pregnancy test when I got home and it's darker than the one I took when I found out yesterday I'm just confused this is my first pregnancy?
