Condom mishap PLEASE HELP

Hey everyone so I’m getting a little freaked out me and my boyfriend have tried to have sex twice once news years <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> (the condom broke he wasn’t inside tho it was just the tip) and once last night I got different condoms and this time it was bunching up. Basically it was inside this time it didn’t slip off or anything but it was definitely bunching up in the tip. I’m scared he didn’t finish or anything like that because I decided we should stop since it was bunching. I looked inside it and there was a little like clear ish substance around it. It wasn’t a lot by any means but idk I do not want to get pregnant should I take a plan b or any other emergency contraception? I’m scared a little of that went in but idk for sure
