The night after I had sex I got really sick and I had the runs. Two days later my boobs were sore so bad. And I been getting constipated with dark green stool. I been feeling really sick in my stomach. And sometimes force myself to eat because I can't eat. At work I'm a waitress so I'm used to a big rush... Well today I couldn't take it I felt so dizzy and would forget what I was doing. I was also sweating like crazy while my other coworkers weren't. Could I be sick or could I be pregnant? I'm 3 days away from my period and my boobs usually hurt 3 days before exact but they started hurting 11 days before my period.
