TTC and put on Provera

I haven't had a period since stopping BC in January. I was put on Provera, 1 pill a day for 10 days. I took my last pill 20 days ago and still haven't started. Is it at all possible that I'm pregnant? I have another doctor appointment tomorrow and I'm super nervous about what happens after provera and no successful period. 💔 anyone have experience with this?
