Reassurance please

2 days ago my boyfriend and I had sex for the first time, and we are sure we did everythong right. I have been on the pill for 8 months now and have been taking it flawlessly for the last 6 months. We Used a condom and used it correctly, and I'm pretty sure there was no brake in it. I know there is almost no chance of me being pregnant, but my boyfriend is still freaking out and really worried.
