Pregnancy scare

So exactly a week ago I had unprotected sex.. well sort of. Things were getting hot and heavy and my boyfriend stuck his penis inside of me for under 30 seconds I would say. He did not ejaculate. There was a little bit of precum before he put it in but it was about a minute before he did that. But for the past week I’ve been so paranoid about being pregnant because my life would be OVER. I haven’t had any symptoms or differences in my body except for the past few days I have had milky thin whiteish clearish discharge and I don’t know what it means really.. I know I have to wait at least another week to take a pregnancy test but I’m just so scared and paranoid and I have been since that day. What should I do??
