I (think) missed one birth control pill.. am I protected?

I take norethindrone (progestin only) at 8pm every day but there seems to be one extra pill in my pack (unless I’m just insane). My boyfriend and I had unprotected sex after this occurred, before I realized. I’ve experienced some light spotting so far... However, usually when I take a pill even 30-40 minutes late,... show more I take norethindrone (progestin only) at 8pm every day but there seems to be one extra pill in my pack (unless I’m just insane).

However, usually when I take a pill even 30-40 minutes late, I get my period/breakthrough bleeding. Am I still protected...? I did some research and supposedly I’ll be fine if I missed one pill. This is on the Planned Parenthood website. I’m just extremely anxious and don’t want any problems.. Thank you all!!
