I am 32 years old, I used a back up contraceptive pill on 29/11/2020 to prevent pregnancy after my last period. As I speak now I am yet to menstruate since Dec until now. I did a blood and urine pregnancy test it was negative in Dec and January 2021.
Do a blood pregnancy test.
See your OBGyn, you need a prescription of provera to have a period.
Stay Healthy!
