Can Noresthisterone Postpone The Periods?

Age 31 height 5ft 2 weight 9 stone. Hi I want to delay my period for a close family wedding. I will be coming on the 30th Aug and then again 20th sept. The wedding is 27th sept. If I take this noresthisterone this month will if mean I come on later next month? I want to delay the cycle so my period does not fall around this time
