So in November I had a normal 5 day period and then December came and my period was like 10 days late an then my period finally started, but it was only 2 days long! then in January my period was like 13 days late and it only lasted 3 days and a couple days later I was sleeping and I woke up at 1am and was having HORRIBLE pain like where I get cramps it was SO bad I couldn’t walk or stand I almost past out from the pain!! I like crawled to the kitchen and got pain meds and took a hot shower and after like 35 mins of absolute hell it finally went away! It was the worst pain I’ve EVER experienced!!!!!!

Does anyone know what could be wrong?? Please help me!!!
