Wondering

I have irregular periods but for the last two months they’ve been fairly regular. According to glow im 3 days late. I’ve been pregnant before but showed no symptoms. And I have no PMS symptoms before my cycle (those oddly went away after my miscarriage before my rainbow baby). So I dont know it have any hints before my period starts or any of that. Unsure if it’s worth taking a test or just waiting it out. Thoughts
