AF was due yesterday but ended up coming this afternoon well I think it did, I have very light bleeding it's a pink an brown sort of colour an I have really bad cramps to the point where I wanna cry! My periods are usually always heavy at the beginning but this one is barely there I only noticed I was bleeding once I went to the toilet an wiped.. It hurts so much an I don't know what I should do! I'm not pregnant obviously, I took a test yesterday which come up negative.. Has anyone had this before and if so what did you do? Also does anyone have any suggestions as to what it might be an what I should do?
