I m a 25 year old female, have a marina coil, so haven t had any periods for 3 years now. I use to be quite a cold person, always first to complain and now I need the window open to sleep and the air con on in work. I m not sweating, and I can t seem to cool down. It also comes with headaches that normal painkillers can t seem to get rid of. Is there anything seriously wrong??
