Late or missed periods can be caused by many things. Most of the time it’s nothing to worry about but see a doctor just in case.
Common causes of a missed or late period include:
- being pregnant
- stress
- the start of menopause
- sudden weight loss
- being overweight
- doing too much exercise
- taking the contraceptive pill
- breastfeeding
Sometimes the gap between your periods may just vary each time. Your periods might come early or late. This is known as having irregular periods.
