May 19, 2012 started my period. May 26, 2012 ended my period. 2 days later I have sex unprotected on May 28, 2012 we had sex without a condom. A week later I started discharging like brown/a little red and my lower part of belly is hard. I GET CRANKY WITH EVERYONE. My period should be coming near da end of June 2012. But Im feeling pregnant. What should I do? Am I pregnant?
