Possibly pregnant..help!

TMI

My boyfriend and I had unprotected sex and he did cum in me. My period is about a week late. But, I’m not showing any signs of being pregnant. It hasn’t been very long but I’ve never had this happen before and I’m kinda freaking out. I’ve taken a pregnancy test right after and it was negative and now I’ve done this other way of seeing if I’m pregnant by peeing in a cup and seeing if it gets a white film over it- and it hasn’t. I have no symptoms as of now and I’m just really nervous. How long should I wait to take another pregnancy test?
