Trigger a Script on On Saturdays

I'm looking at writing a script that only fires off an email when it's either the first or second Saturday of the month..

All other Saturdays of the month can be ignored. The issue I'm having is that each Saturday has a value of 6 when using Get-Date.. So I need some way of ignoring the 3rd & 4th Saturdays of the month.....

So far I using a If statement and a count variable.. but the script still runs when the third Saturday is triggered... As i've reset the counter.... I'm trying to find the best logic to use for this case..

$StartOfMonth = Get-Date -Year $Year -Month $Month -Day $Day
$CurrentWeek = Get-Date -UFormat %V -Year $Year -Month $Month -Day $Day
[int]$DayInWeek = $StartOfMonth.DayOfWeek
Write-Host 'Day Of Week = ' $DayInWeek
Write-Host 'Starting Day Of Month = ' $StartOfMonth.Day
Write-Host 'Day of Week = ' $StartOfMonth.DayOfWeek
Write-Host 'Week = ' $CurrentWeek
$Saturday = $DayInWeek
	If($Saturday -eq 6 -and $Counter -eq 0) {
		Write-Host 'Day Is First Saturday Of Month' 'Day = ' $FirstSaturday 
		$Counter++
		Write-Host $Counter
	}
	ElseIf($Saturday -eq 6 -and $Counter -eq 1){
		Write-Host 'Second Saturday of the Month' 'Day =' $StartOfMonth.DayOfWeek
		$Counter ++		
	}

Any ideas...

Thanks,

Shaun.
