Progesterone pills for TTC

Debbie

Hopefully some one is in my shoes... nurse prescribed Progesterone pills to help me conceive, prescribed for days 14-24 of my cycle.

I believe I was going to ovulate around cycle day 18/19, but I have not ovulated!! Do these pills prevent you from ovulation (which is the opposite of why the nurse gave me)....

Or does the progesterone pills postpone the ovulation until after cycle day 24?????
