My girlfriend is 2 months late on her period after quitting birth control. We've taken about 8 home pregnancy tests within the last month or so; all have come up negative. We're going to planned parenthood tomorrow & hoping to get a blood test. Is it possible that she is pregnant although the tests have all come back negative? I know she's been very stressed out lately but I don't know if that would cause her to be this late? As far as symptoms go (if these even ARE symptoms) she's been somewhat constipated, nauseated every once in a while, somewhat moody but she usually is a rather moody person. I don't know if this is all just stress related because she's going through some difficult times right now, or if she's pregnant.
I'm just freaking out & would just like to know for sure.
