My Week 2 patch had fallen off last Sunday and I was unable to reapply it. I changed the patch immediately and assumed that Sunday would be my new patch change day. My patch change day is usually Tuesday.
I left the patch on until this past Sunday (7 days) and removed it, but realized this might be incorrect. If considering it from a Tuesday change day, this means I did not change it last Tuesday and removed 2 days earlier this week. What should I do?
