Possible Pregnancy?

My boyfriend and i we’re having protected sex and when he finishes he pulls out and he looks at his dick and there is no condom so we both realise it’s inside me so i go to pull out and it’s all wet and i don’t know if the cum went inside of me or not but i’m on cycle day 12 and i have a 27% chance of pregnancy and i’m really worried because i’ve never taking a morning after pill such as ellaone before . can someone please help me x
