Sooo I had my period September 3-8 and my fiancé and I had sex on the day I ended my period and after that we have been having sex like crazy and I’m irregular soo I don’t know which day I ovulate soo I noticed my nipples have been hurting since yesterday and I had cramps like as if my period is about to start and usually my breast would hurt a week before my period but I already had my period and according to eve app my next period doesn’t start until October 9 , So my question is could I gotten pregnant and this time frame?? We are ttc as well .
