Low Progesterone ?

A

I got my progesterone levels measured at 6.5weeks and was just told it's low, at 5.9. I was started on 200mg of Prometrium (progesterone) once a day (pill form). My HCG level was 22,000 which is normal/high. Has anyone else been in this situation? Is this an early sign of miscarriage or is there still hope?
