Im Female And 17. Ive Been Quite Concerned Lately Over

Im female and 17. Ive been quite concerned lately over some symptoms ive had lately. For a week ive been getting the fever but only in my face. The 20th to today i havent been able to eat or sleep. Yesterday I was nauseous all day and got so hot that i puked water and stumach acid. When i do eat my stumach hurts so bad. Ive noticed very light spotting but i am on the pill and shouldnt start my period for two more months. I have been stressed all week but ive never had anxiety so i dont know what this could be.
