Ovulation while on Progesterone


I’m currently taking Progesterone Pills on days 16-25 of my cycle because I was not having a period. My doctor told me I could get pregnant while taking them. I was wondering if anyone knows when I would possibly be ovulating while taking them? I know it’s before the pills start each month but I’m not sure if its the days right before or a week or so before. I’m new to this forum and also trying to conceive. Any advice would be helpful!
