2 periods in one month??

so ive been taking bc for almost 2 years now I just recently stopped my bf and I have decided to try for a baby

I already had my period this month but now I'm bleeding again? my period ended on the 12th

I kept switching pills becausr I was randomly bleeding, crazy mood swings all the time, or it just made me hurt to the point I couldnt even stand being touched and sex was so painful. I was taking ortho try cyclen lo

is it just a hormone imbalance thing or should I be concerned?
