LH strips

Stephenie

Soooo i decided to purchase ovulation strips to see when I’m fertile. I’ve never used them .. just wondering if they worked for anyone ? I know the kit says both lines (the control and test line) must both be dark in order to be positive. So i tested yesterday and it was the first time i saw two dark lines, so ofc we had sex lol and i tested again today and it’s faded. Can someone help me and explain this to me ?!
