Provera and Ovulation Stimulation. When prescribed for women trying to get pregnant, Provera is usually given for 10 days. After that time a woman can expect bleeding from two to 10 days later.
Best Answer: It's considered normal for your period to take up to 14 days to arrive after your last dose of Provera. Personally I have taken Provera 3 times to start my period; two times I started my period the day after my last pill, and once I started 9 days after my last pill. I took Aygestin (another form of progesterone) this month & I've been spotting since yesterday (day 4 after the pills).
