workflow with wait periods - how can I see where contacts are in within the flow?

 Hi,I was wondering if  there was a report I can use to see where my contacts are within my workflow (see attached)

I was checking the campaign automation summary report. i'm looking for a report that will tell me for example: your contacts who have entered this workflow and have checked 'over 3 months' -> was sent 1st reminder email -> and is currently in wait period at day 60 of 90.

The reason why I am asking this is because the program of 2nd reminder email in this workflow, although it's shown here, there is actually no finalized email content in this program yet.
