I’m 21 and have never had a period in my life. My doctor prescribed be medroxyprogesterone 10 mg to start my period. She seemed to think I could still could get pregnant. Me and my boyfriend had an accident and we both freaked out so I took a Plan B just in case while on my medicines. It’s day 10 the last day of my pill and no period. Do you think Plan B could affect the medroxyprogesterone?
