PMS symptoms or early pregnancy symptoms?

The first day of my period was on April 7, 2019 & I had sex on the day 5 of my cycle (April 11, 2019). We did the pull out method (1st & 2nd round) but I'm still worried because he did not pee after the first round and there might be some active sperms in his pre cum during the 2nd round. Around April 17, I started to experience some PMS symptoms like headache, bloating, breast tenderness, nausea, abdominal cramps. On April 19, I had a lot of thick, white, creamy discharge, which made me worried and paranoid. A while ago, I've been experiencing lower abdominal cramps (dysmenorrhea) because according to this app, I am supposed to have my period tomorrow. Am I experiencing PMS symptoms or early pregnancy symptoms? Help me, ladies! Thank you so much! ❤
