Okay, I have a sistuation. Me and my boyfriend have had lots of unprotected sex, and I haven't gotten my period in a month and a half, but I took two pregnancy test (First Response) and both came back negative. But I took them about 3 weeks ago thinking thats when I should've gotten my period. I think I'm going to check one more time, but I'm having lots of sypmtoms of pregnancy. Things like sore/tender breast, more discharge, tiredness, headaches, nasuea, lower back pain, frequent need to go to the washroom and I always have the munchies. Anyone got an ideas of what it could be? Help please =(
