My period comes regularly every month without fail.
A housewife in her late 30s with two children.
I have come every month without missing a single one.
But since 8 years ago? Even before having my first child
The cycle gradually became shorter, and it shortened to 21 or 22 days.
Because of this, there are times when I do it twice a month ㅠㅠ
My situation is like this.
Is there no way to extend the cycle to 30 days??
