What happens when I get my period?

Menstruation occurs when the uterine lining sheds, some two weeks postovulation, when a pregnancy has not happened.

Menstruation necessarily follows ovulation. A bleed without ovulation is either a withdrawal bleed, which occurs on some forms of hormonal birth control, or a shedding of the built uterine lining during an anovulatory cycle (a cycle without ovulation).

DAYSY DETAILS

Daysy asks that you record a minimum of 3 period days. Daysy incorporates this information, that you experience a period and when it starts, into its calculations, and as such, this information is vital for an accurate calculation of your fertile window. Most women will experience a period for longer than 3 days, but some may experience a two day period. With Daysy, menstruation is considered bright red flow, while spotting or brown blood shed is not needed to be included in recordings. As Daysy gets to know you, you will see flashing violet lights to, at first, ask if you have your period, and later, to predict your period is due.
