Hi, currently I'm using femilon contraceptive pill for about one year. But during the time of the periods to happen, that is after the 21 day period or in between the 7day period we are about to celebrate our annversay. Therefore I need to delay my periods to happen later in the month avoiding these dates. So is it possible using the femilon like without discontinuing after 21 day period till the day I want my periods to happen?
