3 days of positive opks?

I know I just posted a thread yesterday.. but I keep getting these darker edge lines. Do these count as a positive? This morning the test line showed up faster and darker, but this darker edge is throwing me off. I thought the whole line is supposed to be the same color.

It is common to get multiple days of positive tests. The average surge lasts about 3 days although I've had positives up to 8 days before. Some tests are also more sensitive than others. Just keep BDing if you can and you should catch the egg!

What brand tests are these if you don't mind me asking? Mine I got off of Amazon are so hard to read. The control isn't even as dark as that one! I would love to buy this brand.
