Ovulation

Can anyone help me out with this. I am due to ovulate tomorrow according to glow, I thought it would be Tuesday as that’s normally right in the middle of my cycle but these are the results I am getting! I thought after Yday test today it would be positive and I would ovulate then monday or Tuesday but it’s a barely there line today. Did I somehow miss my surge? I did test later yday and it was same as the one earlier so I didn’t take a pic of it. So confused and disheartened now. I made sure I didn’t drink too much so it’s not that it’s been diluted. Do I keep testing tomorrow and see?
