Blood tests showed I have no progesterone. So doc perscribed me medroxyprogesteron which is Provera right? Anyways doc said to take 10 mg once a day until I start my period. Then later said to take until all bleeding stops. She gave me 30 pills. ALSO My prescription info says to take 5-10 days once a day. So what information is right? All info I am reading says take for only 10 days. I called drs. Office twice and cannot get a direct answer? I have been taking for 7days now. What should I do? Whose instructions should I follow?
