Question: how long does it take to start your period after taking medroxyprogesterone?
Answer: You will usually take 10mg each day for 10-12 days beginning on the 16th day of a 28 day course of oestrogen therapy. Your period should occur 3 to 7 days after starting Provera. If you do not have a period after you finish a course of Provera, check with your doctor in case you are pregnant.
