I recently got my period and I am on day 3 today. Usually during my 3rd day, I end up feeling extremely hot and I sweat, I feel dizzy, I feel like I also have a fever and I can't sleep at night time either. Does that happen to anyone else? Is that normal when you are on your period? And sometimes I get a lot of gas that ends up giving me a lot of pain, that it makes it difficult for me to walk. How can you prevent all this from happening?
