Ok so I take 2 HPT's they both show 2 lines (meaning pregnant) even though the lines are faint, they're showing up within a minute of taking the test. My doctor did a blood test and it was negative, I take another test the day after the negative blood result and it came up positive with a faint line. Still having symptoms, my breasts are filling up, peeing constantly, still nauseated, little sharp pains in my abdomen. But it's only been a little over a week that I even thought I was pregnant a few days after sex. I know it's too early, but why would 3 tests come back positive, and the blood test come back negative? Can anyone help? Please. I know i can't imagine seeing the lines, my son's father saw them too.
