Condom.....

Need more advice.. Should I take plan B? Maybe its stupid q.but I need to know...

I had protected sex about 7 hrs ago, when we checked condom we didnt see any hols. Than we throw out condom outside on snow (car sex)lol, than he wanted to check once more and condom was broken(we are really carefully)... So should I take plan B or not? He said that he didnt ejaculated inside me.. I'm scared that myb there is any hols that we didnt seen early.. so here we are
