Nuvaring fell out

I had sex with my boyfriend without a condom yesterday (he didnt cum in me) and the ring fell out without us noticing. I didn't realize it until earlier today and then had to wait to get home from work to find it.

After I did I looked up what to do and it can be reinserted and continue to use it if it it had been in for 2 weeks or less, so I did

Only it had been at least 24 hours and I'm supposed to be a peek chance of pregnancy, how worried should I be?
