Hi I am now 1 day late, however the last 5 to 6 days I've been have very very light brown discharge on and off... I wouldn't know it if I wasn't wearing a pad.. I've also been feeling really queasy at random times in the day, headaches and the last 2 days I've had pee way more frequently than usual, there really hasn't been much cramping but there's been tightness, I have taken 2 tests but both were negative, please help, does it sound like I am?
