Hello, my period is usually due around the 20-21st but yesterday (23rd) I had drops of blood in my urine and on the tissue but just a pink discharge on the pad. This morning (24th) I had some very light pink bleeding, enough to change a pad. 2 hours later, I had lots of watery discharge (as if I had pee'd on myself) and it was a tint of pink. I am now experiencing horrible cramps and semi heavy bleeding with quarter size clots, what's happening?
