Thanks for your question. It can be normal for women to skip some periods even if they are not pregnant. There are many reasons for missed or delayed periods. The most common causes are pregnancy (as you have mentioned), breastfeeding and menopause. Other reasons include a recent change in weight (either weight loss or gain), stress (such as emotional stress or physical stress from illness or very strenuous exercise), medication side effects and hormone problems.
