LH Help - High vs. Peak?

Ariana • Proud Mama to Rainbow Baby Boy 🌈👶🏻

Yesterday I received a positive OPK where the test line was the same color as the control line (the bottom two strips are from the same day). Today I tested again and the test line is so much DARKER than the control line. I was wondering if anyone could please explain the difference between getting the positive and the “peak” today? Either way I’m planning on BD’ing a lot. lol

Thanks in advance ladies.
