Doctors say I’m normal so what’s going on

Hey y’all, I got off birth control back in October and I completely skipped the month of November. At first I thought maybe it’s because my body is trying to straighten itself out. Well no, I had a cysts rupture on my ovary. (Worst pain I’ve ever felt) anyway, now I’m 30 days late. I went to the doctor because I’ve been having a lot of pain down there and I was spotting lightly. Her and I both thought maybe I had PCOS (I also gained a ton of weight since I had been on birth control). Bloodwork came back and I don’t have it. Okay....so like now I have super late periods, spotting here and there and I’ve gained a crap ton of weight and nobody knows what’s going on. Okay cool. Great. Loving life. I still have pain down there, feels like my period is about to start and my boobs are almost always sore. I don’t get it. Like at all. Has anyone else dealt with this? Also my periods were normal before I got on birth control.
