Ovulation test

Taylor • Married -Army-Family 2 years ttc praying for our Rainbow
Ovulated 22. But why I still keep getting a second line. Like usually 2 days later after my ovulation day it will be only 1 line. Is it normal? Or it could be anything wrong with me. 11 months trying for our rainbow. Af due 10/8 this month we got Preseed and was my first month getting my test line as dark as the control line.
