Stressed

Hi! So my boyfriend and I only have sex using condoms and I am on the pill (Cryselle 28 days). We just got back from the Bahamas and I found an active pill in my jewelry bag I may have missed but haven't missed any before/after that. I don't know which day it's from but it is an active pill. He uses a condom and pulls out when he ejaculates. Should I be concerned?!? I don't think so but I'd like opinions haha
