I had sex with my partner 6 days into my first row of birth control, but we used condoms as back up.

We had sex on the 6th day of the 21 day pills, but I had protected sex. We used a condom, and I know nothing felt risky. I don't think I have any reason to believe I'm pregnant or at a a big risk of becoming it, but l'm paranoid. Other than that, I feel like I just need reassurance. Am I okay?
