Hi, Looks like a surge could be on it's way! Are you temping as that's the only way to confirm ovulation has occurred. My ovulation sticks would stay dark for a couple days then I'd ovulate a couple of days later, so sometimes 4 days after my first positive opk.
Bottom one looks like you’re almost there so I would test again tonight as the surge sometimes comes really quickly so you might miss it if you test tomorrow morning. I’d say dtd tonight just in case so sperm is there if you ovulate tomorrow or Saturday. I’d also recommend an app such as femometer that reads your opks and calculates when ovulation should roughly be.
