Following is an example of a calculated member in Time dimension Weekly hierarchy to get all full weeks from the last three months:

Aggregate(Filter(
  [Time.Weekly].[Week].Members,
  DateBetween([Time.Weekly].CurrentMember.StartDate,
    DateSerial(Year(Now()),Month(Now()) - 3,1),
    DateSerial(Year(Now()),Month(Now()),-6)
  )
))

DateSerial(Year(Now()), Month(Now()) - 3,1) returns the first date of the month 3 months ago,
DateSerial(Year(Now()),Month(Now()),-6) returns 7 days before the end of the current month to exclude a week which starts at the end of the last month and ends in the current month; if all weeks which start in the last month despite their end dates should be included, then write 0 instead of -6 - it returns the last day of a previous month.
