Emergency please

Hey girls i have a question. Im on pill since 2017 regularly ( last 5-6 month i’ve never miss a pill always on same time). This month we had some rubbing with panties and when we had sex we were always protected with a condom+with drawal. Today my period should be start but it didt start. I have yellow-white mucousy discharge and last 2 week i have sore boobs too. I know this is imposssible but can i be a pregnant?
