WHAT ARE MY PREGNANCY CHANCES?!

My fiancé and I were having sex about an hour ago and the condom broke (we are on vacation in Bora Bora) and forgot lube. We only use condoms when I'm not sure if my pill is working. For example, I usually take my pill at 11 pm and I took it at 4 am instead.

The next day at 9:00pm, the condom broke and he ejaculated inside of me. I cannot find Plan B anywhere here and I am worried. My period is 7 days away.

Could those 5 late hours effect the pills usage for today? Could I get pregnant because of that?

I am 22 by the way. Thanks much!
