It's the weekend so I can't call my doctor, Dr. Google is upsetting, so can anyone tell me if this has happened to them?

I've been taking Loloestrin for several years with no problems. In fact, I pretty much stopped getting periods. This past week, I got my period while on the active pills. And it's still going, longer and heavier than I've had in awhile. I'm not sexually active, nothing big has changed medically for me recently, what is going on? I have had a bunch of ovarian cysts before and doctors think I have
endometriosis. This is a pain in the butt, and other body parts. Has anyone had this happen? Can you tell Google that I don't have all the cancers?

What makes things most difficult is I live in a place far from most medical care and my doctors are across the country. I'm moving to another remote place soon. My chosen lifestyle does not fit well with too many medical issues.
