Ovulation strip test

Lizzie • Pregnant with baby #3 😙 Team Green 💚

Has anyone used these tests before? I have been using them the last 4 days because my app says I am ovulating ( supposedly) but nothing is showing with these and they are a little tough to read.

What are some ovulation test kits that you guys have found the most easiest to read / accurate.

Feel like I'm possibly wasting precious O days 😶
