No longer a virginnn butttttt

Rose
So I just had sex for the first time (Whoo hoo!) and so nothing went wrong or broke or anything. We used a condom and I'm on birth control but I'm still kinda nervous That something was messed up and I don't want to be pregnant! There really is no reason for me to be nervous I am, but I still am. Should I take a test? This might sound silly but when should I take it to get the most accurate results? Thanks! Any other advice would also be helpful!
