I need to know if my situation is at all normal. I am 19 and have had normal painful periods since I was 13. Last month and this month, however, I start cramping almost 2 weeks b4 which isn't normal for me. Those cramps are unbearably painful. I feel like I'm going to vomit from the pain. It effects my entire back and buttocks as well as my uterus. It almost feels like a sharp stabbing spaz rather than a cramp. I also bleed only during sex even when my period isn't due for 3 weeks. I don't know if it's normal or if I should go to the hospital. Please please please help me! Comment your thoughts/ experiences! I greatly appreciate it ahead of time!
