Will I get pregnant ?

So I want to stop taking my birth control because I think it's making me depressed and I get really bad mood swings. My boyfriend came in me two days ago and I took my birth control that day (as well as all the previous days ) but didn't yesterday and don't want to today so that I can go off the pill so I can be happy and Also I probably won't get my period of the predicted week which will be nice cause I'll be on vacation. But was taking my birth control that one day good enough to protect me from pregnancy or should I keep taking it a few more days before I go off my pill?
