clearblue digital OPK smiley but weird lines under?

[psychochick]

I've been using clearblue digital OPK for months now and never had this problem. Today was my first smiley which does match expected timing but usually I pop out the stick under to check the lines and it is usually just two lines as usual OPKs are. But this one is a really weird diagonal thing that looks like dye run I guess? But I used it exactly the same as always and didn't move it so I'm just wondering if the smiley is even valid.



Has anyone else run into this before? Should I trust the smiley? Thanks

Hi.. i don't think the lines make much difference? I have noticed when i get my smiley that the lines on the stick itself aren't necessarily the same intensity as the control line xx
