Suggest a pill

Payal

Hi.. I had unprotected sex on my fourth day I.e on 5th september of my period but his sperms didnt come inside my vagina.. i didn't had any pill but now after a week i am bit worried and nervous. I am not getting any symptoms like nausea or cramping but if at all do you suggest me to take any birth control pill now? Or should I wait for my next period and if at all my periods doesn't come that how do I terminate it please help
