Meh...

The past 2 nights I had taken my BC pill late by at least 20-25 min due to being inside of haunted attractions (not like I’m going to stop right inside of a haunted attraction in the dark to take it 🙄) but I’m on the mini pill norethindrone. Should I be worried about it that I was only late by like 20 ish min? Most importantly am I still protected? When is a pill considered late/Missed when being on the mini pill?
