Would you pack a test?

I'm 12 dpo today. Took a test (Dollar Tree) and it was neg. AF is due Saturday (May 31). We leave Friday for a 2 week vacation. The area we're staying doesn't have any big stores, etc. there is a grocery store in the next town (6 miles north) that I guess maybe would have tests if AF doesn't show. I don't have any in hand so I would need to buy one if I want to take it. Would you pack one just in case??
