Need advice for delay mens

Hi po nag make love kame ng bf ko nung jan 1 and last period ko is dec 3 this month ng january delay nako ng ilang araw pero masakit naman puson ko. May posibilidad ba mabuntis kahit withdrawal naman at wala sperm na napunta sa private part ko pwera nalang sa dibdib? #pleasehelp #advicepls
