First of all, don't worry! I am right here with you and freaking out myself. I have PCOS so I take Metformin (2000mg). I am also taking progesterone and prenatal vitamins. I had a miscarriage in November (3 months ago) and another one in 2006. But I also have two daughters, one born after my first miscarriage.
There is hope. Don't give up! Those pills are all meant to be a help to prevent another miscarriage from happening. And the great news is that you don't have to take all of them the whole pregnancy! Just until 10-12 weeks along. So look at them in this positive light. Also, a low HCG level this early on is not a bad thing. The point is that they need to double every 72 hours.
