Your Menstrual Cycle

For most women this happens every 28 days or so, but it’s common for periods to start sooner or later than this, ranging from day 24 to day 35.

Your period can last between three and eight days, but it will usually last for about five days. The bleeding tends to be heaviest in the first two days.

When your period is at its heaviest, the blood will be red. On lighter days, it may be pink, brown or black.

You’ll lose about 30 to 72 millilitres (5 to 12 teaspoons) of blood during your period, although some women bleed more heavily than this.
