A slight delay in your period is generally considered normal. Most menstrual cycles range from 21 to 35 days, with an average of 28 days. So, a delay of up to a week or so is within the normal range for many women.
However, there are many factors that can affect your cycle:
- Stress: Significant stress can cause hormonal imbalances, leading to delayed periods.
- Weight changes: Sudden weight loss or gain can disrupt your cycle.
- Exercise: Intense or excessive exercise can also lead to cycle irregularities.
- Medical conditions: Certain medical conditions like PCOS, thyroid problems, or even infections can affect your menstrual cycle.
- Medications: Some medications, such as birth control pills or antidepressants, can also cause delayed periods.
If your period is delayed for more than a week or you experience other unusual symptoms, it's important to consult a doctor.
