Pregnant or period will come ?

Had sex 3 times after period ended. And my next period is suppose to start today and still not here ... should I be okay ? Everytime we did it, it was protected and he always pulls out before he cums. And the last time he did not cum at all (3 days ago ). Symptoms I have rn are sore breast , sick to stomach a lil , white discharge, dry vag, cramps and yesterday I had this very very very light pink dot on my toilet paper but nothing else .
