While having intercourse I found out brownish liquid from my vagina. My periods have got over 4 days ago for this month, and I was having intercourses after 20- 25 days . I used to get white discharge during ingercourse which was normal but this is the first time I have seen brownish discharge. Also I am noticing that my breasts have become heavy and they pains. I thought of checking pregnancy but I am having periods regularly every month.
