My period came on on feb. 6 and the other one came on mar. 21 it was the longest period I had since i first started. It was back to back and the normally for me is every two to three months. On the last period for four days i was spotting and the last three days it was normal. After i came off my head has been hurting almost every day. I have been trying to throw up but it goes back down and i have been sleeping more than i use too. I would like to know what is going on with my body???
