Missed pill

Hi! First time poster so sorry if this question has been asked before. I’ve been on ortho tri cyclen lo for about 2 weeks and I️ accidentally missed my 6th pill (white). I️ didn’t take it once I️ remembered because for some reason I️ thought you couldn’t take 2 in one day (which I️ know now is wrong). I️ just skipped my 6th day and continued taking my pills normally, pushing back the cycle by one day. I’m now getting worried that this has left me unprotected. Is someone able to shed some light on what it means for me to entirely skip one day and push back the cycle? Thanks so much! :)
