Late period.

Im on day 37 of my cycle and I still havent gotten my period yet. I typically dont have a regular cycle, can range between 28-38 days. I feel like it might be because I was stressed as I was busy moving. I did a home test 2 days ago and came out negative. I also started getting sore boobs a few days ago so probably will get my period later. But not sure if I should just wait it out or do another test with another brand?
