hi my gf has been experiencing a brown discharge during foreplay and then after sex it is soaked through the sheets. It's brown as if its old or dried but its from the sex. It's happened probably the past 5 times we've had sex. I think she is pregnant, but we use condoms and b/c.. she has every symptom of being pregnant for almost 2 months now but she doesn't look pregnant and she took a pregnancy test right when the symptoms began and she was in the clear..maybe a freak pregnancy due to her sportaic period the past few months...she misses it for 10 days.. then she only spots for one or 2 days.. any ideas of what it could be???
