Periods on the pill

Hannah • momma of a 👼🏼💕
I was on depo, came off of it and then didn't get my period for 6 months, so my OB started me on a bc pill to make AF come. I just had AF 2 weeks ago, and now it's here again. 
Should I keep taking the medicated pills? Should I be concerned that I'm getting it more frequent? 
I've never been able to take the sugar pills because AF always comes before I get there.
