plan b

So we had sex on 6/25/17 which was the first day of my ovulation and the condom broke he ejaculated inside by accident this was around 4pm maybe 5pm we looked in multiple stores for a plan b but they didn't have them... finally we found one at a cvs and it was 9pm I took it... now it's the 3rd day... (knowledge that sperm can live up to 3-5 days and my egg which isn't supposed to be released until 6/30/17 and it lasts 24 hours) could I get pregnant ? Do you guys think there could be a possibility? I understand that ec plan b doesn't always work for some women but I did take it as soon as possibly could and within the first 24 hours
