I got my last period on June 6th ending around June 10th, today is June 26th and I started having some brownish bleeding, through the day i have had a little brownish redish and pinkish blood but it is not bleeding to the point where I need a tampon. I have been having intercourse since last month but my boyfriend has been pulling out. Is there any chance this can be implation bleeding? If so when can I take a pregnacy test?
