Pregnancy scare

This guy and me never had sex but I’m afraid his pre cum went in me cause he pressed on my vagina but I told him I’m waiting on having sex. He did though do it multiple times unprotected and it was my first day ovulating according to the app. What’s really got me freaked out is that my boobs hurt sooo much. They never do. I’m suppose to start my period tommorow but I’m having so much panic. Do u think I’m pregnant? Be honest please. What should I do? I took a sugar pregnancy test and it dissolves when I mix it when I don’t it just lays on the bottom..
