I haven't had sex in a month, except for anal sex, during the time I shouldve gotten my period all I had was brown discharge. Now my breast hurt, and I get cramps like I have my period but I don't. What does this mean? I highly doubt I'm pregnant, because it's impossible to get pregnant through anal sex...... Should I even bother taking a pregnancy test, or should I wait to see if I get my period, because it just may be a change in cycle........ ?
