Provera?? is this normal?

So I am on month 3 of medroxyprogesterone(Provera.) dr is having me do 3 months, 10 days on the pill each month to try to regulate my period. The first month I got my period about a week after the last pill and it was TERRIBLE, which I expected since I hadn't had my period in a few months. The second month I got my period the day after the last pill, and it was lighter than the first one. I take the pills each month on the same dates. I finished the last pill on Tuesday and haven't gotten my period yet or any sign of it. Is that normal? Should I call the dr? Or just give it a week and call if I don't get it after a week? Please any advice is great, I just figured since I got my period the day after last month, that would happen this month too. I'm not stressed about anything new so idk if that's normal it hasn't come yet.
