Why did your doctor prescribe this? It is prescribed for a total lack of menstruation for 6 months or more, a thickening of the uterus lining or abnormal uterine bleeding.
It is unlikely but not impossible that you are pregnant. It can however take a few cycles to work.
If you have more pills for next cycle, it is important that you do a pregnancy test before taking it. These pills should not be taken when you are pregnant.
Your doctor should have asked you to follow up with her after a few months? The best is to speak to your doctor.
Best of luck TTC!
