Is it possible to feel pregnant even if my period isn’t due for another week? There’s these little things here and there that are tripping me out, for example: I’m nauseous, sore perky boobs, hot flashes, extremely tired, gas and frequent (more than often)bowel movements, etc... some times I think I’m just getting sick, but then again I did have unprotected sex 2 days before ovulation. Help?
