my period started on 10th of july and ended on 15th of july. we had unprotected sex on 21st of july. sex was rough but after that i was spotting for a day and cramping. Nausea, bloated, uncomfortable on breast. I have 26 period cycle. My period was delayed with unusual dark brown spotting and less bleeding than normal days. My period started on 9th of august. I am still bloated, crampy and nauseaus. One feeling says its pregnancy but since i have period, i feel its can't be possible. What do you suggest
