Discharge questions

So today I start my fertile cycle, and my discharge is clear but not super sticky. Monday/Tuesday/Wed it was like egg white and clear, and then yesterday it was white and cloudy. My boyfriend and I did have sex last Saturday, but he pulled out before he came. It took him a bit to work on himself to cum. It was his first cum but it was without a condom. It happened the day my period finished. I’ve heard it’s possible to get pregnant from pre-cum. Should I be worried or is this normal discharge process?
