Not sure what's going on

I started bleeding lightly in the middle of April and was bleeding the whole month of May (lightly) and when I do get my period I bleed heavy and when I was suppose to get my period like around there I stopped bleeding completely. Not sure what to think? My boyfriend cums in me like all the time but I think because I have ovarian cyst, that affects me getting pregnant. Not completely but somewhat. We were ttc but gave up kinda. I haven't had cramps at all. Only once I felt dizzy and light headed, but I was by smoke from the grill. And my boobs have been feeling sore and sensitive for about 2 months I would say. They Been feeling like that for awhile. Only felt like throwing up once. 
This has never happened so I don't know if I should be worried or what 😮
