please help me


I might sound dumb but I need to know. i had unprotected sex on my ovulation day which was from the 4-10th usually I get my period by the end of the month like I got my period on Dec 2017 I got my period on the 28th then on January 2018 I got it on the 24th so my question is this??? my boobs started to hurt today but I still have 2 more weeks for my period to come.. usually my boobs hurt a week prior to my period. is there a possibility I might be prego or am I ovulating until right now or what?? I'm very confused 😫😟 or my period night be coming sooner than I thought.
