Birth control “period”?

Kelly

I was on birth control for a while and I bled like I was on my period. I had terrible migraines to the point I almost vomited. I also had cramps and all of the other side effects that come with a period. I’m due for my regular period in about a week. My question is, should I expect it after the weird off schedule “period” I just had? Anyone else had this issue that can shed some light on this for me?
