What do you make of this?

These are my opks cd13-23.

The 3rd one from the top seemed positive (cd14) but now the bottom lone looks the same (cd23) I'm confused. I also had spotting twice. Cd19 I had brown spotting and Sunday cd23 I had red and pink spotting. This cycle is confusing the crap out of me. Any ideas what's going on?
