2 months after plan B

So in early April I took a plan b pill about 5 hours after having sex where the condom slipped off. A week later I bled for about 5 days, a week passed, and then the week after that I bled again for another 5 days. I have had sex once between then and now and everything seemed to go smoothly that time, no faulty condoms, but my period is 10 days late. I know some people's 2nd period after plan b can come super late, like I've heard 2 months or 45 days, some craziness like that. I know it's probably all in my head but what are my chances of being pregnant? And has a super late period 2 months after plan b happened to anyone else? And how likely is it for me to get pregnant between now and my next period?
