Last cycle I had a chemical pregnancy right before five weeks. The highest my hCG got was 49.2 on July 14th. I started bleeding for a week. My doctor wants to do day 21 and day 23 labs we believe the chemical pregnancy was due to low progesterone. My levels was 8.14 so he prescribed me progesterone supplements but I think it was a little too late if I start taking Progesterone supplements at 3dpo will that affect my results of days 21 and day 23 results? I just want to make sure if I get pregnant again my levels doesn’t cause another chemical pregnancy.
