Mira chart Help!

Ka

Hey! So I am TTC baby #2 and been having irregular periods after I had my first baby. I tried Mira this time and am so confused by it. It says I definitely ovulated (i think lol) because my LH rised to 30, at least what I tested. Then it dropped. The part I am concerned about is that my PDG shot up to 21 1DPO and now at 2DPO it is at a 3?? Is this bad? I thought it was supposed to increase each day? Does this mean I'm already out?
