Condom Accident

So me and my boyfriend did it yesterday and I found out the condom broke when I went to the bathroom and peed. I seen a piece of plastic on my underwear and thought it was the other piece of the condom and it smelt like cum so that's why I knew it broke but to be sure I looked at the condom we just used and tried to find the hole and yep there was a hole. Me and my bf were so worried and scared but we went to the store to get a plan b pill (which is basically an emergency pill for accidents like mine, etc) and I took it like 10-15 min after we had sex so basically same day. Supposedly the pill is most effective if taken asap. Ive done research on it bc im so paranoid. But am I gonna be okay?
