Okay, I'm only 15 years old turning 16 and a couple months ago when I first started my period I got a horrible heat flash, or so I think it was. And now on the first day of my menstrual cycle there's about a 5 minutes where my body over heats and I start sweating really bad and it feels like I have a bad fever. I try laying under my fan or using an ice pack but it does nothing and eventually it goes away after a couple minutes and I'm fine. I don't think it's menopause.. Is there anyone else who has this? If so, what do you do to get through the heat? Do you have an idea of what causes or triggers this?
