I haven't had sex in about 2 months now. I've had 2 regular on time periods. So it would seem. I've always been a skinny person with a flat stomach and now my jeans are snug and I'm getting a baby bump which seems to get bigger throughout the day. I've taken tests that come back negative. The symptoms I'm having are lower back pains, cramps in lower abdomen, heartburn from time to time, nausea occasionally but never get sick, gassy, use the bathroom more frequently, always thirsty but feel sick at the same time? just random not normal for me things. I don't know if I should wait it out or go to the doctor being I don't have the money to just go get a negative blood test. Any help would be greatly appreciated. I've had pregnancy scares before, but they were due to getting on and coming off of birth control. I keep telling myself I'm thinking too much and its all in my head, but when it comes down to it I can't ignore the signs. Lol.
