tmi!!! something popped

So bear with me on this i was going number two and had to push a little well while i was pushing it felt like something in or close to my left ovary popped there was severe pain but then it dissipated some but still in a little pain what could have happened and what should i do and could it have anything to do with my period being gone for 6 almost 7 months

Update: woke up this morning feeling super nauseous and as far as i know i dont have a history of ovarian cysts
