I have 4 apps

Yes, I know it is a lot :)

According to Glow im 19dpo(days late) , My tracker, 18dpo(5 days) , Flo, says 16dpo(4days) and Petal 13dpo(4 days) .....Do you think I should test or wait a bit more.

Sidenote: I started exercising in January... 2 of 3 days a week and last I couldn't go to gym to due work. And started a new healthy diet. Can these two factors have an effect on my cycle?

We've been TTC for 17 months now, so i really hope this is it!!!
