Best looking opk yet

So after yesterday's downer day and rant.. In a more positive state if mind today. Got up early did house work, went to the gym and decided to take and opk as I've had light cramping  on my left side. Nothing major just noticeable. So I took an opk and this is what I got... I've never had one this dark before. And I've got pcos and currently on cd 136. Do u think this could be positive? Maybe god heard my prayers yesterday​
