I have been on birth control for about one year now, I felt a little off (nauseous, severe anxiety). I took a pregnancy test this afternoon and first one was a book error (clear blue). I did another one and was shocked to see pregnant. I had my husband go to the store and get another test and he got a different one abd showed not pregnant but the blue line in the control window isn't showing up. I haven't missed a pill, but we did have sex when I was ovulating. Happy but shocked and trying to handle it as well as we can . Can this be possible? Has anyone had this experience?
