I took a pregnancy test today, it was negative, and i am one day late. my fiance is deployed and before he left we were having lots of unprotected sex, several times in mid jan. there was no pulling out. i have been feeling extremly tired, irritated easily, my boobs are heavy, stomach pains, headaches, slight nausea, i throw up once, heartburn. if anyone has any ideas on if this sounds like i am pregnant and what i should do? i am 21 and i dont have anyone here to talk to this about and really would like another persons opinion. thanks!
