OPK's

I promise this will be my last question/post regarding OPK's :-)  I am using First Response OPK and I got two dark lines but here is my question. Does the line only have to match in color or does it also have to match in width? They lines seem to match in color but one line is much thicker than the other.  Thanks for any help you ladies can offer.

I'm not sure if the brands matter b/c I used a Walgreens brand OPK.  I believe as long as the line is just as dark or darker then you need to at least spend the next 3days getting busy!  I dont think the width matters too much.  Good luck!
