6 days late. Should I test?

So tomorrow will mark a week late on af. I'm unsure if I should test because my period was weird last month so it was a little later than usual. Glow made it so I should start later this month because of that and still nothing. I have cyst issues and I have been feeling kind of crampy but like I said no sign of my period. What do you think? Should I test or wait? I apperciate any input! Thanks :)
