Morning after pill

On my day 7 of cycle, I had sex with condom on. However, when my bf took his pe*** out, condom was half way around it although he ejaculated inside condom. But it was only half on when he took his pe+++ out. Now I am not sure if i some of the sperms leaked inside or not. Am I overthinking? Should I take morning after pill? I’m just afraid of its side effects.
