When should I test!?! praying for my BFP 👶🏽🌈

Natalie
Okay ladies!
I'm 13dpo according to glow. I'm currently on the 2nd day of missing my period and I'm dying of anticipation! I'm hoping this is it & we've finally conceived our rainbow baby!! 
I know we've all been there a day or two late and prayed for our bfp... maybe this is the one I've been praying for! Please send me all your positive vibes & baby dust
When should I start testing? Is tonight to soon??
