The Menstrual Cycle

The menstrual cycle is a recurring cycle of physiological changes in women of reproductive age. It is regulated by hormones, the brain and the women’s reproductive organs. Each menstrual cycle, your body prepares itself to support a potential pregnancy. As you approach ovulation each month, your uterus becomes more welcoming to sperm, allowing them to survive longer and swim to the egg; which increases your chances of getting pregnant.

If you have intercourse during your fertile days and fertilisation occurs between a sperm and the ovule released that menstrual cycle, the resulting embryo will implant itself in your uterus, which will develop a thicker lining (or endometrium) and better blood circulation to support the growth of the embryo.

If fertilisation does not occur, no pregnancy is achieved during this particular menstrual cycle and hormonal changes will then trigger the thickened endometrium to slip away. This is the start of your menstruation (or period).

Each menstrual cycle begins on the first day of your period and ends on the day before you get your next period. The menstrual cycle is composed of three different phases and its average length is 28 days, in which case ovulation is expected to occur between day 11 and day 16. However, it is not unusual to have cycles which are as short as 24 days or as long as 60 days.
