Total sum for consecutive period

Hello Dax gurus!, 

 

I have the count for each consecutive month  in the below screen shot. What i want to get is the values in the Total column. For each consMonth 1,2,3,4....., i want to add up the values in the count column. 
May 20 = 1

Jun 20 = 1+1

July 20 = 1 + 1 + 2

 

Aug and oct or not consecutive months so the total start again in Oct and so on. Here is the output i am expecting:

    Hi,

    Total =
VAR ThisStartMonth = 'Table'[Startmonth]
VAR FirstMonth =
    CALCULATE (
        MAX ( 'Table'[Startmonth] ),
        FILTER (
            'Table',
            'Table'[Startmonth] <= ThisStartMonth
                && 'Table'[consMonths] = 1
        )
    )
RETURN
    CALCULATE (
        SUM ( 'Table'[Count] ),
        FILTER (
            'Table',
            'Table'[Startmonth] >= FirstMonth
                && 'Table'[Startmonth] <= ThisStartMonth
        )
    )

    Regards
