Some girls have sever cramps, and some experience little to no cramps. For me personally, it differed from period to period. Sometimes I'll have horrible cramps, sometimes I'll get lucky and have none.
I did before I was pregnant. I got them after my period was over too. The cramps and other pains from other things got so bad at some points that I had to take Vicodin. I still get these weird period like cramps even though I am pregnant. Most people do get period cramps unless they take certain pills or shots. Birth control shots can lessen those feelings in your body. So can disposable heat wraps though they're not as good. Hope I was helpful.
