Ovulation test Question

This is my first time using an ovulation test.
I've read that the test line needs to be as dark as the control line to be positive.
I got AF on 9/15-09/19 and got this on 09/29
Then I tested again on 09/30 and got this. Even though the control line isn't as dark, does it mean I am was still fertile.
We didn't baby dance on 09/29 when we got the positive but we did the next day. Was that too late?
