Can I take a plan B again?? SOS PLEASE

Hey ladies so last week Friday the 13th my pussy got murdered and my bf nutted in me... an hour later I took plan B and I’ve gotten symptoms like discharge, nausea, random cramps so I know it’s working, so today makes a week since I’ve taken it and I still haven’t gotten my period which I know is normal because it’ll either come on time or early... so today me and my bf want to have sex again and I want him to nut again in me though... and well can I take plan B again? Would it be affective or would it be bad? I know I need to get on birth control but I’ll get on it after I get my period... but can I take plan B again? Or should I not risk it?
