I'm freaking out

Okay I know everyone is going to say this is stupid and that I shouldn't be having sex if at some point I thought I was okay but I had sex with my boyfriend last Saturday and we went for a second round using the same condom I know it's so stupid but I just wanna know if anyone else has done this and been fine. Please no comments just telling me that it wasn't right and that I could be pregnant because I clearly know that I just need something to calm me down because at this point I don't even know how to relax and wait for my period anymore.
