Missed birth control pill risk?

Hello F/18 here, I fucked up and had so much on my plate I forgot to take my birth control pill yesterday. I missed it entirely. I take the combination pill called Apri.
I missed the 2nd day of week 2. However I took it when I remembered and took today’s dose.
I did have sex maybe 3-4 days ago, I’m i at risk or anything or is it just a mistake?
