Ok I was on Birth Control pills for about maybe a month and a half but then I suddenly stopped. While I was on B/C and off I was having unprotected sex with my fiancee. Now out of nowhere a few days after sex I had brownish/pink discharge. I thought it was birth control. My breasts are so tender and sore. I'm about 5 days late of my period. I pee alot now. Increased hunger and I am VERY tired no matter how much or good I slept the night before. What could it be? Pregnancy Or Paranoia?
