I have really bad period cramps/pains please help its urgent?!

I'm going on a mini holiday with my boyfriend, our friends, and a few of my close girl friends. We're going to america so its a very long flight! I'm on my period at the moment only my boyfriend knows, I get really bad cramps/pains and nothing can help them not even medicine! What am I going to do basically squashed up on a plane!?? Please help me?? :/

Try sucking in your stomach and then releasing. The only reason you get cramps is because of how your womb is not used to being used. Bananas are supposed to relieve pain too. Try paracetamol aswell!
