I had sex on the 12th of July and the guy nutted in me twice that night and my period started that Thursday after it was normal for 2 days,but then it went to light to me not having it for a day and going to very light again. I've felt tired lately and hate the smell of food and don't hardly want to eat like I use to all time.. I feel like throwing up everywhere and I don't know what to do please help.
