I havent been on my period since October, My period is all over the place i can miss 2 or 3 months then decide to come on. Last month around the time i was due on i started get cramps in my stomach like i was due on but i found nothing. Last week i took to pregnancy tests and i came back negative. I keep getting pains in my stomach. And today i have been so hot i feel like someone has put a heater right next to me so i put the fan on my to cool me down but as soon i turned it off i felt like i was burning up.Does anyone know the reason why?
