I got my period April 1 and on April 14 my boyfriend and I had unprotected sex and he came inside me. This is not the first time we have had sex. The next day I had light brown spotting and the day after that I had slightly heavier spotting. Could this be a sign that I am pregnant? I have never had this before and I am not supposed to get my period until April 29. My periods are always regular which make me think I could be pregnant since we had sex the 14th day of my cycle even though I had these signs 2 days after sex. And I am not having any cramps.
