Wondfo OPK question

Wild_flower25

I have the blue handle ones.  Do you think it takes longer than 5 mins to get an accurate result?  I look at it at 5 mins and its negative, but at about 10 mins, its positive.  False positive because its too late?  I have had ones that have stayed negative past 10 mins so I'm just not sure.  

What is your experience?  At what point do you get your positive?

I don't have a digital to back this up today, otherwise I would.  They're expensive so I'd love to just use the Wondfo.  

 

thanks for your help

5 minutes. By that point the background is usually white and all the extra background color is gone. Just the line/lines left. 10 minutes is probably too long.

To have a positive OPK both lines need to be the same darkness (or test line even darker than the control line)

It seems that mine take a little while too, try just dipping the tip in rather than up to the max line.
