Period Sickness? Please Help?

OK, I just woke up( it's 4AM where I am) and I have the most good awful stomach pain, I mean it's really bad. I'm 12 and I've had my period for two years now and I always have a little stomach pain, but right now it feels like I'm going to puke... A lot. It just started yesterday and came full force, I can't even stand straight, I have to hunch over. Is this normal?
