Should I be okay?

Ok so I had drunk unprotected sex Sunday, he did not ejaculate at all I’m just scared of pre cum pregnancy ....my period is suppose to start in 8 days and the symptoms I have right now are sore breasts, fatigue, bloating & gas, farting a lot , white discharge, should I be fine ???? I’m 19 and don’t want a baby so I’m getting an abortion if I am pregnant .
