I had unprotected sex on June 12. I know that the pull out method was not smart at all and there is a possibility of pregnancy, I get it. Not smart choices. But I usually get my period the 3rd week of the month. So last week, at the time I usually get my period, I had Dark brown spotting for a few days instead. The brown discharge stopped, and this week I have very clear & stretchy discharge. What could this be?
