If then Statement using Two Different Date Ranges

In Power BI, I'm using a period table that applies steps to take today's date, sets up the ranges, transforms the ranges into a table, and then sets the output in Power Query. Everything works as it is supposed to but the focus is at the ranges step.

Here it is as is:

    = {
                    {"Day", 
                    Date.AddDays(TodaysDate,-1), 
                    Date.AddDays(TodaysDate,-1),
            1},
                    {"Week to Date", 
                    Date.From(Date.StartOfWeek(TodaysDate,Day.Thursday)), 
                    Date.AddDays( Date.From(Date.StartOfWeek(TodaysDate,Day.Thursday)) , +6), 
            2},
                    {"Week", 
                    Date.AddWeeks( Date.From(Date.StartOfWeek(TodaysDate,Day.Thursday)) , -1), 
                    Date.AddDays( Date.From(Date.StartOfWeek(TodaysDate,Day.Thursday)) , -1), 
....

Here is the example output:

What I want however, is that if today is equal to Monday, then only show the date for Friday. Here was my attempt:

= {
            {"Day", 
            if Date.DayofWeek(TodaysDate) = 1 
       then 
    [
            Date.AddDays(TodaysDate,-3), 
            Date.AddDays(TodaysDate,-3),
    ]
            else
    [
            Date.AddDays(TodaysDate,-1), 
            Date.AddDays(TodaysDate,-1),
    ] ....

Notice that "Day" is "Yesterday". I'm trying to get this done so people can see production for the previous day worked where the previous day for Monday would be Friday.
