Worried

On Monday I went in for my first prenatal. I thought I was 8 weeks but baby was measuring 7 weeks with heart rate of 128. OB thinks that since I have PCOS and my periods were irregular I must have ovulated late. In Tuesday they called letting me know that my progesterone was low 11 but not low enough to be too concerned but she still went ahead and ordered progesterone... for the past 3 weeks my symptoms were there and now they are completely gone. This has me so worried that my baby is no longer there. I'm so glad my OB was able to fit me in today for another US and a visit with her PA....Hopefully it's good news
