OPK ??

Aleah • Mom of 2 boys TTC #3 for 17 months 2 misscariages

This is my first time using these.

The 1st is on CD 10 at 2:30am, 2nd is also CD 10 at around 6:00 PM the 3rd is CD 11 at 2:30 am.

My question is the one at 6pm CD 10 still has a strong line than the other 2. Maybe it's because the other where taken at 2am? Or does it matter. And when should I take the next OPK?

Is the 2nd test positive or no?
