Weird pain

Okay so I've had a lot going on with my health lately I have a doctors appointment today but I'm freaking out so I thought I would post on here to see if this has happened to anyone else. Last month I was three weeks late on my period I went to the gyno because I knew I wasn't pregnant and needed to find out what was wrong. I found out that I had small cysts on my ovaries and they told me they should go away on their own and once they did my period would start. So a couple days went and sure enough, my period started. I need to backtrack here because I've also had some bleeding in my belly button that seems to be linked to my period. I'll start my period and then a couple days later, my belly button will bleed. So lets day forward back to the now. I'm 19 days late on my period this month, having crazy pains in my right side, had extreme (almost went to the emergency room) pains after sex last night, I get migraines every day almost, and I just all around feel like crap. Has this ever happened to anyone else?
