Me and my boyfriend have had sex without protection for the past 4 months but he always pulls out and when he is about to cum he pulls out and even jack off a lil bit to cum. Im not on any birth control. Ive been a lil sick to my stomack lately but I dont have any simptoms like cramps or tender breats. I dont even feel simptoms for my period. What  does it mean? Am i pregnant or just panicking?
