I’m on vacation in another country and period is late

So my period is late by 2 days. This never ever happens. My period is the most regular I’ve ever seen. Anyways. I’m in a whole different continent from my home. Sort of different weather but not sooooo different. Different food for sure. I took a test today could barely read it because the instructions and language were hard to figure out but it was negative. My question is, could it be late from being in a different country? Different food habits etc. only been here for about 5/6 days. Please need insights period is NEVER late.
