Okay, I had sex Oct 6 and I had my period on Oct 19. In november I was really sick, nausea, fatigue, lots of saliva couldn't stand smells so I had a blood test, it was negative. however, i still have these movements in my stomach. I think i'm pregnant because i sleep alot, but i had my period for oct, nov and dec. anyone have this happen? I think i'm pregnant what should I do?
