Crampzzzz

I've been getting wicked cramps for a month or so now. I've had two periods (one on xmas and one a week after New Years) and I usually don't get periods at all with the birth control I'm on. Idk if I have an ovarian cyst (I had one about six months ago) or what but I know this isn't normal. Also, idk if this is connected, but I feel sick every once in a while. Pls help ty ty💕💕
