For about two weeks, I've been feeling really tired in the middle of the day and like I want to climb into bed a couple hours early. When I eat something, no matter what it is, I feel nauseous ranging from that feeling one got in high school when about to give a presentation and full on "I better stay within 3 yards of the bathroom, just in case." everyone once in a while I get these crazy dizzy spells. I can be sitting at the computer or up cleaning, it doesn't matter. I've started having this problem where one second I'm fine, the next I have to pee so bad, I need run to the bathroom. I took a home pregnancy test and it came up negative. Could it be wrong? Should I go to the doctor? My period was also due on the second.
