Condom broke

Okay so I'm not super worried but I thought I'd see what your opinions are.

So last night when my man and I were having sex the condom broke and we didn't notice until he had came and went to take it off. Honestly, he's more freaked out than me about this. I just started taking the pill like 3 days ago, and my period also just ended so I don't think I'm in my ovulation period, but to be sure I took a plan B pill the same night. So like yeah I probably should be good right, but I was wondering if I should take another plan b pill just to be safe or is it not worth the money?
