Plan b or not

Me and my bf had sex the condom broke outside of my vagina and there was no cum I’m scared and I don’t know what to do I took plan be in January of this year idk if I can take it again . But a long time ago we had unprotected sex and we used to pull out method and I ended up being ok idk what to do . Also the apps says I’m about to start my fertile window. We had sex on Friday and I have one more day to take it idk if I should tho if he didn’t cum ... he also rubbed his thing on my vagina on accident but he said there was no cum or anything on it so idk he said that the condom broke when he took it out
