discomfort after severe pms cramps?

yesterday morning my period arrived 3 days early and I've had SEVERE pms cramps for almost 5 hours straight and ever since then I've been having discomfort in the uterus/lower pelvic area and subtle pain along with this every now and then sick feeling. i took 4 aspirin because I was in so much pain. Is it possible that my cramps were so severe that my uterus hemorrhaged or torn or something? or did I take too much aspirin? I'm a hypochondriac so Im worried I may be overreacting. note: I had protected sex two weeks ago, but the time then and now is too long I think? im only 17. another note: I have a long history of abnormally severe cramps, to many points where I almost needed hospitalization or even begged to go to the hospital. Before the arrival of my period and the severe cramps, I felt fine. I'm currently resting because the cramps were so severe I have felt sore (in the uterus area) and tired. What do you guys think? I hate hospitals so Id like to know what to rule out before making an unnecessary visit. I really feel like my cramps damaged something finally....
