Hi I ended my period on the 30th of November, my boyfriend came to visit the following weekend. We had sex all weekend, and then that Monday November7th i was bleeding a little bit, i thought it was from having sex, but as the days went on i continued bleeding and appeared to have a lighter period. 7 days later i was done.....What can this be? he started to freak me out, and thinks i should go see a doctor...
