How Period Delay Tablets Works

Period delay tablets operate by mimicking progesterone, a hormone naturally released in the second half of the menstrual cycle, which helps maintain the lining of the uterus.
By artificially maintaining high levels of this hormone-like substance in your system, the usual drop in progesterone that triggers the breakdown and shedding of the uterus lining (menstruation) does not occur.
As a result, taking Period delay tablets effectively delays the start of your period until you stop taking the medication, at which point the levels of the hormone-like substance in your system drop, triggering menstruation.
