Provera

We have been TTC for about 15 months. I️ had a miscarriage last year and was diagnosed with amenorrhea a few months later and my doctor put me on Provera. I’ve been on it for a while but I️ started taking it on 11/3 and took my last pill on 11/13. But still no AF. Is that normal? I️ usually start within a couple of days after I️ start taking it so idk what’s going on. Idk if it’s normal... or if I️ should call my Doc... take a test... I️ just wanted to see what others’ experiences have been with this
