Awful pain

About 6 months ago I got off of my birth control for many reasons. Now the last couple months my periods are now 2 wks apart, its ridiculous. I am in so much pain. Last night I was in so much sudden pain that I spent an hour or 2 just puking, it was awful. Now this morning I still haven't eaten anything because I'm afraid I'm going to get sick again because obviously I still have pain its just the beginning of the period. So sick of this.... haven't had a massive pain period like this for a while. Hoping I can get past it. Seeing my GYN on Thursday, hoping for some kind of bright light from her. I need some good news for once. All I can say is I hope I don't have another night like last night.....
