Sooo feb 8th-13th was my last period. We had unprotected sex 3x on the 17th of feb. Fast forward to March 6th..I have weird brown Discharge with a little bit of pink blood in it. Pregnancy tests are negative so far. Now today on the 9th, barely any blood at all. My periods are normally bloodbaths. I’ve been more emotional than usual. And I craved hot Cheetos and Mountain Dew together which I only crave when I’m pregnant. What does this mean?
