OPK Reading Help

GE • Fri, Aug 19

This is my first time using the line style OPKs (I previously used the first response digital which were horribly inaccurate)...it looked to me like the test from 8/16 had the darkest line though not as thick. Does thickness matter? I just want to make sure we don't miss our window! Thanks!
