You will not get your period while taking fenmatone. This is because the drug Finmastone is a drug that contains estrogen and progestin. The estrogen contained is estradiol, the most active estrogen in a woman’s ovaries, and the progestin is digestrol. When taking the medication, you will not get your period. It is usually taken from the fifth day of menstruation, starting with the white pill for 14 days, followed by the gray pill for 14 days. The difference between the gray pill and the white pill is that the gray pill contains progesterone. When all 28 days of the pills have been taken, you will get your period only after you stop taking the pills. This is because the endometrium loses the support of estrogen and progesterone after stopping the medication, and withdrawal bleeding will occur, so you will not usually get your period while you are on Fentanyl.
