Hi im asking on behalf of my girlfriend as she refuses to go to see a doctor. She keeps getting really hot (and dizzy i think) or feeling really cold , she s had a constant headache the past 4 days and says her head feels heavy and sometime she just feels really out of it. we ve wondered if it was pregnancy but took a morning after pill after the incedent where we thought she may have gotten pregnant and did a test 2 weeks after which was negative. i m just worried as she wont go see a doctor and it doesn t seem to be getting any better. what could it be? thank you
