Opk positive?

This is my first month using opk's. Yesterday's test definitely had the test line lighter than today but I am not sure if this is a positive. Are both these lines the same color?  If so, does this mean I already ovulated?  I'm 34 With PCOS and only 1 ovary I am not even sure what my chances are of this working. My husband and I have been passively trying for a little over 2 years. Trying opk's and temping for a few months now before going to get tested to see if there is something wrong so I need to make sure I understand what I am seeing.
