Ok so is that why it is taking me so long cause the doc gave me some pills to start my period that still haven't made it come on

WHY did the doctor give you these pills? Did you get a pregnancy test first?

Yes he gave me one bfore I startrd taking it

Could you be more specific? WHY did he give you pills to start your period?

My perios wouldn't come on cause I was on depo shot but I been of it for 7 months and haven' had a period do thy did all kind of test all can back normal so he gave me some medroxyprogestero pills I had to take them foe ten days and my period was suppose to come on one to ten days after but it has been almost 3 weeks now

And why haven't you called or visited the doctor that gave you the pills instead of asking here? We don't know why you were given these pills, and we can't do your follow up exam. You need to call your doctor and tell them that the medication did not work for its intended purpose.

I know that I wanted to know could I get pregnant with my situation

There's no way for us to know that. We are not gynocologists and have not examined you. You need to go to the doctor and ask this question.
