I have been really terrible about my birth control. My boyfriend and i have unprotected about twice a week and the cum always stays inside me. I was supposed to start my period 6 days ago, and for 4 days before i was supposed to start i was getting light brown and white discharge. And instead of getting my period, I have had light brown like watery discharge of some kind, and for a couple days, when i would wipe, there would be a dark brown mucus like clot, but not really a clot. more stringy i guess. its there every time i wipe, no red blood at all. I need to know if i'm pregnant, but everyone says its too early. and the tests i have taken say negative. any insight?
