I am six weeks today and just started progesterone supplements on Friday. My HCG levels were not increasing like they should, but my doctor never mentioned what my progesterone levels were. I asked her for the supplements per comments of friends and family and she wrote me a prescription... Just trying to see if they will help me or not. I don't know what is more important during a pregnancy - HCG levels or progesterone levels?? I have my first ultrasound this afternoon and I am extremely nervous
