Pregnant period birth control

Sooo my period usually lasts around 5 days and yesterday I was on my third day when me and my boyfriend decided to have sex. (I take the pill and I’m diligent with it). When he pulled out the condom was broken and I started to panic. Sperm lasts 5 days at most so it’s very unlikely I could get pregnant and I take birth control so that lowers the chances even more. I need some reassurance that the odds are in my favor of getting my period next month
