Ok so I was supposed to start my period on the 14th. When I went to the washroom I wiped and it was light pink and it only lasted about 1 hour. Then the next day the same thing, but it only lasted like 10 mins. Then yesterday a it was red, but when I when back to the wash room it was light pink, then gone.. now it's nothing, but mild cramping. Can someone give advice of what they think it might be?
