birth control efficiency? *help me pls

Georgia

so usually I take my first birth control pill on Sundays, but I got so busy this week i didn't even pick it up from the pharmacy till Tuesday and didn't take my first till Wednesday morning. is it still effective? and if so, how effective? I've been on bc for three years, I'm usually pretty on time with everything. I have my late days here and there but overall usually I'm very strict about being on time
