Recently I got a really sore throat and it was nothing at first but recently I've been feeling really weak and sick and I always feel like I'm going to throw up my throat is tight and i feel light headed and get headaches I had pregnancy symptoms and I thought that was the reason because me and my boyfriend had sex two weeks ago but the test came back negative I've had sore throats before but never like this :/ I get really emotional as well and I wasnt like this before and all throughout the day I feel extremely tired and then at night I can't sleep
