Should I be okay ?

. Period is two days late, could I be pregnant ? I’m getting so sad and paranoid don’t wanna be pregnant . We had sex the 16, and it was protected and he did NOT come inside me .. he never came in me at all. I have sore breast, fatigue , slight cramps , very emotional .. etc. IM not ready for a child . I really don’t wanna get pregnant. Put water in condom to check if there any leaks but there were no leaks
