I been having unprotected sex for over a month now, I got my period on the 22 of August and ended on the 6 of September so my period lasted about 2 weeks, on the 7th or 8th I had unprotected sex again and had sex again 1 night ago. After we had sex this time I went to the restroom and was bleeding like a brown and pink blood, and it's been about 2 days now that every time I wipe its a little brown and sometimes pink?
