My doctor suggested me to take regestrone 5mg for 3 days(one in morning and one in night) and told me that after 3-4 days of stopping the pill i will get my periods.. its 4 days today after stopping.. can i start taking regestrone again to delay my periods further as the main reason of taking the pill is to not have periods from 21st-24th for big event at home. does taking regestrone again from today till 24th morning help delaying my periods until 24th.
