HELP!!!

Its currentlt 3:47am and I am having the worst cramp/period pain flare up EVER. I took two extra strength tylenol already but about 20 mins ago i have woken myself up with bad cramps, a feeling like i really need to go #2, and nausea. I dont know what to do. Im on the toliet but nothint comes out. Its so heavy I dont know what to do. Is this normal for a 14 yr old?
