Is this my surge?

This is the first time we are trying naturally in awhile as we are taking a break from IVF! Wasn’t fully confident that I would even ovulate this cycle due to all the meds/hormones from my recent FET cycles. Also I just had a chemical pregnancy, unfortunately, from my last FET, which I believe caused me to ovulate a bit later—I’m at around CD 20 today.

These tests are all AM/PM, and it looks like tonight’s first line (bottom test) may be darker? Is this my surge? Or is it pretty much the same color/darkness as the other line? Is it supposed to be noticeably darker where the second line is actually faded? Thanks in advance🙏🏼
