I am on birth control and i have sex without a condom on a regular basis. I am supposed to get my period this week but yesterday i started “bleeding” w/ a lot of white creamy discharge with some light pink blood and later throughout the day just some light brown spots. I am sorry for the details, i just want to be thourough. The last week and a half or so i have had very sore breasts, is this implementation bleeding and am i pregnant?
