Progesterone to help with TTC

Hello All!

Back in April of 2018 I had my nexplanon removed and have been TTC since May of 2018. Since then my periods have been super irregular, only really had 2 periods with several spotting days. In December I went to my doctor and he put me on progesterone pills.

QUESTION: who has take these pills and any success stories ? How long did you take the pills before becoming pregnant ?
