When to test or know to test

Jewel

Ok so while I am tech "avoiding pregnancy" on the app right now. If i were to get pregnant my boyfriend and I will be happy. We aren't using any protection and we do not pull out. We both have the app and we both log daily....if i do not have symptoms of pregnancy...when should I test or should I just wait for my period. It's due in 3 days. Just wait for it to be late? Or what?

Lol, it's been 7 years since I been pregnant. I'm stupidly lost on this haha.
