Ovulation test strips help

Chloe

I came off the pill in December had my withdrawal bleed a few days later. I had my first normal cycle in January 28 days. Glow predicted me to ovulate today but my test strips aren’t dark enough yet. Do you think it’s coming or because of the pill it gets to a peak and then stops? I will keep testing cause it looks like it’s getting darker just wondered if glow was just a rough guide?
