So the other day I was in the shower and started bleeding. It was dark though and very confusing. Then the same day every time I went to the bathroom and wiped it was there. Well today I took a shower and it was like a brown discharge and it was thick. I'm on birth control and I start my period on Friday. At the moment this is the 3rd day this has been going on and idk what to do or what to think this has never happened before
