Not fully actively trying

I'm a mom of 2 boys and would love to have a little girl. If this is God's Will. I have an app to keep track of AF and at the same time i have an indication as to when I O. Last month I thought it was the month, just to be disappointed with a heavy full force AF. This month I took a different approach. Not focusing too much on every symptom. Not looking at my DPO per day. Just relaxed. So currently I am a week before my period, well according to my app. Or I might be 5 days as I started 3 days earlier last cycle? I dont know? So I don't know it's too early to test?
