Accident regarding birth control

So I had an extremely stressful week and I am a Sunday starter with my birth control pill, but unfortunately with everything going on I forgot to get my birth control until Thursday, missing 4 days. So I proceeded to take Sunday, Monday and Tuesday pills on thursday then on Friday I took Wednesday, Thursday and Fridays pills. I had sex earlier this week and again this weekend not even realizing it was my most fertile days. Is there any chance i could get pregnant from this if I continue taking my pill as I'm supposed to?
