normal?

a lower jawline blackhead/pimple showed up, really gassy, constipation but also feeling the urge to go constantly, lower abdominal cramps that come and go, tender nipples (only when touched), burping a lot, little to no cm when any comes out it’s thin and milky white. AF is due in 6 days am i PMSing? i didn’t engage in vaginal sex nor am i on birth control but i did engage in oral sex around my fertile window and my bf says he didn’t have sperm on his fingers (mutual masturbation) before he put them inside me, couldn’t there be a chance of pregnancy. stressed and paranoid any thoughts?
