dermabond only lasted 3 days?

Anyone have dermabond only last 3 days? it's a 3 ml incision and it just fell off. I was told it should last about a week or more. the cut isn't open but I'm afraid it may in a wrong move. It didn't get wet I assume it's from activities.

*already called the doctor. he said it should've lasted at least a week but it it stayed closed just keep it clean and dry. Just wondering if anyone elses came off early and how it worked for them
