Confused.. 10 Days Late

Hello! So somehow my period managed to be 10 days late without me noticing.. 🤷🏽‍♀️ I was getting ready to buy a test today when I noticed some light brown spotting when I wiped. None on my underwear and the only “symptoms” I have been having is extreme fatigue and some light cramping. Should I skip the test and wait for my period to come?
