Condom stuck in vagina👀😬😅👎🏽🙀

Hello everyone. Recently I had sex and the condom became lodged into my vagina after he ejaculated inside of it(this was on Sunday😁) He was able to pull out the condom as soon as he realized it slipped off which was 30-40 seconds😖.He actually stopped in the middle of intercourse and told me all about it😳. My question is(may be a dumb obvious question) is there a high chance of me becoming pregnant from the condom getting stuck inside of me. After he pulled it out, I did we semen inside of the condom but you never know if some fell out or not.👀 (I believe that's possible) I've only had sex with two guys(this one being my second) so I really have not been through this before. I'm going to go get the emergency contraception pill today just so I can be more prepared. I know all of the effects that comes when taking the pill💊💊💊. I was just wondering how high is the chance of me getting pregnant.
