So I'm 18dpo tested negative at 16pdo five days late I always come on time and  never late so I text the guy and was like I'm five days late and he going to text back I didn't come inside of you like what a jerk clearly we had sex multiple times and we didn't use protection nor did he pull out  could he be right ?? Or should I test again been having symptoms like fatigue, cramps on and off, and nothing else is he right about me not being pregnant?
