Should i test?

I am a few days late on my period according to a couple of my apps. Although my periods are never exactly when my app says, they are close. We are trying for a baby and had sex around ovulation day (used ovulation tests). Should I take a test or not yet? One app says I’m late by 3 days (the one I use most), one says 6 days and the other one says I’m suppose to start my period tomorrow (the one I never use). Should I take a test? I really don’t want to see a negative 🥺
