Late while on the pill??

I’ve been on the pill for over a year now. I have always taken it within 10 minutes. Last week I took it almost an hour late. I had unprotected sex on the 24th of Feb and he came in me. My last period was the 29th -3rd jan/feb. it’s always spot on with my app. But now I’m 2 days late. I always have unprotected sex with my boyfriend but this is the first time I’ve been late.

What should I do?
