Advice please!

OK so I tested yesterday and it was a clear negative. Which tells me my period should be coming. But it's late. But I'm scared for my period to come because it seems like every month the cramps get worse and worse. They are so bad I can't sleep and end up crying in the middle of the night and I can't eat with them. I have taken midol and pamprin even Tylenol and Advil but nothing seems to work for me. Do you guys have any advice on how you get through you cramps.
