PEP has lots of side effects, some permanent. I wouldn't take it - one reason is you had zero risk.
Your fear that she took the condom off you to hide it somewhere (because you have taken a wild guess that you won't give up that it was broken which you have zero evidence to believe) after having sex with you makes no sense. She only cares about herself so is likely protected all the time and negative. You probably didn't even have sex, since you were drunk - but that's just my guess and I wasn't there.
