Because many women ovulate around the 20th day of their cycle
One of the methods to predict ovulation is calendar method. You just check you menstrual cycle and calculate ovulation. e.g. If you have a 28-day cycle, ovulation starts around the 14th day of the menstrual cycle.

Ovulation is the natural process in a woman's body wherein an mature ovarian follicle ruptures and produces an egg. It's part of a woman's menstrual cycle and usually appears on the 14th day after the first day of menstruation. You can predict ovulation by checking out the cycle of your menstruation. If you have a 28 day cycle, ovulation usually comes on the 14th day after your 1st day of menstruation period. You can also check if your ovulating through charting your basal body temperature, cervical mucus changes and through the use of various ovulation kits.

No, if a woman has no menstrual cycle then she cannot get pregnant. The menstrual cycle includes ovulation, no ovulation means no pregnancy.
