Hi, I've Been Worried About A Possible Pregnancy, But Here's

Hi, I've been worried about a possible pregnancy, but here's some backstory. My boyfriend pressed his penis hard against my vaginal opening, but he was completely dry, and we didn't go any further than that. I have taken 3 at home pregnancy tests and all were negative. I have had a period since the situation I mentioned as well. I have been paranoid from things I've read online. Please help me.
