Hi I was about one week late on my period and am never late. I've had pregnancy symptoms such as frequent urination, lower back pain and trouble sleeping and fatigue. Foods that were never spicy before are really spicy now. Over the last few weeks I've had pink spotting on and off and yesterday I had dark red(brick color) bleeding. It's generally only when I wipe and only a spot or two on the pad. Generally my period gets heavier on day two. Today is still the same brick red with brown and only when I wipe. I am on birth control but missed the last two pills and it was my first month on it. I had sex during the last two active pills that I missed. I felt like I had ovulation symptoms about four days later. I also took two FRER test which came back negative. What's the possibility of pregnancy?
