what's wrong with me

Leslie
So this happened to me twice this month , I got my period but they were very short. The first one was 3 days and very light. The second one was 2 days and very light as well. Only the first day of both had blood clots and all. I took a plan B in August and I was also on birth control. (Still am ) idk if that affected me. But I'm so bloated to. All these period symptoms. Ughhh. Someone help. What's wrong with me.
