Should I be worried?

So, I messed up, we had sex the day before my ovulation day, and he came in me. I realized this was the case about 24 hours after and took plan B, (which I’ve only had to do once before) but have had NO side effects when before it caused me period to come 2 days later and last a week and a half. I’m super stressed about it, I know the earliest I can test is 6 days before when my period should start, but that’s still 3 days off… and even then not always accurate. The not having side effects has me SUPER stressed rn. Any insight/advice would be greatly appreciated.
