Confused with my OPK test

Hey guys! This is our first time TTC and Its hard to read between the lines as I feel like my test look

all the same. Last period was December 23. I do have pcos and this is my first time <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a>. I started on 1/14 and I feel like all my test look the same except the one I took at 6pm 1/14

which is below that one. The last test was this morning...I am testing in the morning.... should I not do that? What do you guys think about these test? TIA
