New to Clomid & Progesterone?!!

Em
I know I already posted a question related to Clomid but basically my Doctor is treating for PCOS and become pregnant. She prescribed me Medproxyprogesterone and Clomid. She wrote this down on a piece of paper because this is sort of rocket science to me lol. I've never had regular periods so this is all new to me. My question is Do I stop taking the progesterone once I get AF and go ahead and take Clomid? Or do I finish the progesterone even when I get my period and still take he Clomid at the same time? Please someone explain this to me I'm confused....
