When I was 20 we went to a doctor to see why I never had menstruation,he gave me birthcontrol pills,I take it everyday,and when I have taken all of it already, after 5 days I will have my menstruation but when I stop taking this pills nothing happen,ill have no menstruation...

My question is... can I still get pregnant if I continue or discontinue taking this pills?

This is something you will have to discuss with your doctor. There are many reasons for amenorrhea and we cannot diagnose this over the internet. There are some women who still ovulate, yet do not get their monthly menses. I am one of those and have had 4 children, so it is possible.

Please discuss your concerns with your doctor on your next visit.
