First time mom and progesterone levels

I just found out we are expecting on Monday. I had my hcg levels checked Wednesday and they were great. They said my progesterone was low (6) so they had me start taking 200 mg last night, and had me test again today. Of course I won't get the results until Monday! Was just wondering if anyone else has had to take supplements and had a successful pregnancy? I have Pcos and had a chemical pregnancy last month, so I'm really praying that this month is our month and that we will get a strong, healthy baby!
