pain and fatigue

I am 14 months postpartum and stopped breastfeeding 2 months ago. My period is just getting back to normal. I had extreme pain during my period last week... it was on my right side, I think it might have been my ovary. It hurt so bad I couldn't move. My period ended last sunday. Now, for several days I have had bad period like cramps, back ache, bad bloating and fatigue. I have been googling and think it could be an ovarian cyst, endometriosis, and am even worried about ovarian cancer 😕😕 I have gotten myself so worried! I'm calling by gyn Monday. But does anyone have any experience with any of this?
