I had sex 5 days after my period ended, by the next day I expirienced headaches, bloating with slight lower abdominal pain as if I have gas in my womb, , skin irritation, tender breasts and they feel heavy.. It also feels like my body gained abit and not to mention restless nights, extreme fatigue during the day, frequent urination , increase in vagina discharge, high labido and very emotional . It's been 7 days since I had sex,.. I took a test today day 7 post sex in the afternoon and came back negative, is it possible that I could be pregnant?
