Who has dealt with ovarian cysts?

Hey mamas… who all has dealt with ovarian cysts? I went to the hospital last week with extreme stomach pain- i can handle pain but i was in tears hunched over… i got no diagnosis… they took blood and did an ekg, gave me toroidal and sent me home… everyone i have talked to they are saying it sounds like an ovarian cysts that ruptured. I am fine now- haven’t had the pain since 2 days after the hospital. But i had a question for anyone who has or had them regularly… does it affect your period? Make it irregular or anything? I am on the pill and the iron pills started last Sunday and i still haven’t gotten my period yet… it almost ALWAYS comes regularly because of the pill, maybe differs by ONE day but i still haven’t gotten it and its kind of worrying me a little. I do have a doctor’s appointment on the 31st, but i couldn’t get anything any sooner. Please help my brain from over thinking
