How does it work?

When you reach puberty, your ovaries start producing oestrogen and progesterone. These hormones make your womb get thicker once a month and ready for getting pregnant.

Meanwhile, their are hormones also signalling your ovaries to produce, and release an unfertilised egg. In most women, this happens once every 28 days or so.

No fertilisation = getting your period

In general, if you don't have sexual intercourse around the time of your ovulation (when your ovaries release an egg), it's unlikely that any sperm reaches and fertilises your egg. So what' happens is your uterus lining that has recently thickened, will be shed as menstrual blood. And you get your period! This cycle is called menstruation.
