Period Problems?!?! 10 points!?

Okay, this is my second period ever, and it just started this afternoon. I went to go to bed, its about 75 degrees in my house and within ten minutes on laying in my bed I was drenched in sweat. I looked up night sweats but I can only find it about people going through menopause... anyone have any tips to get rid of this? Its driving me crazy :(
