Why is my period late if I’m not pregnant?

Many women have irregular periods and there may be different reasons for this; possible reasons for a late period include:

• Stress: stress can have a major impact on the body and can cause your menstrual cycle to be disrupted
• Body weight: being severely overweight or underweight can affect your menstrual cycle
• Thyroid problems: thyroid problems can disrupt the normal functioning of the hormones in the body, which can affect the menstrual cycle.
• Medication: certain medications, including the contraceptive pill, can sometimes alter your menstrual cycle
• Early menopause: this is very rare but it could be a possible reason

Sometimes a period can be late and then the cycle goes back to normal but you should see your doctor if this becomes a regular problem, as there may be a medical reason and this should be investigated.
