Yesterday i started on provera (medroxyprogesterone) and ferrous gluconate. now i feel like i am pregnant, why?

Progesterone: Dominant hormone of early pregnancy that is also found in abundance in "the shot.".

Are you pregnant? : 1st step would be to check a home pregnancy test to make sure that you are not. Provera (medroxyprogesterone) is a form of Progesterone and it can cause some people to feel this way. Ferrous gluconate is an iron supplement. Iron can often cause unpleasant GI side effects.
