Should I call my doctor

I seen my doctor on Thursday he prescribed me Metformin 500mh, Clomid 50mg, and provera 10mg I believe. My cycles are irregular and Ive not had a period since January 12th, he told me to take the provera after I’ve had my period and 30 after I take my last dose of Clomid If I am not pregnant. I just want to get started 😔😔
