-- Posted by Anonymous at 7:50 pm on May 11, 2008 I had sex with a guy I've been dating last thurs. he's my second and i haven't had sex since august. saturday night i noticed i was spotting, not bad, kind of a brown-ish color. Could it be implanation bleeding, or mean i'm pregnant. A condom was worn and I'm really afraid, does it normally show up just 2 days after or could it be something else?
