Understanding Your Menstrual Cycle and Late Periods

A menstrual period is considered "late" when it hasn't started by the expected date based on your typical cycle length. While the average menstrual cycle is 28 days, it's normal for cycles to vary in length, typically ranging from 21 to 35 days. Tracking your cycle can help you understand your body's patterns and identify when your period might be delayed.

How This Calculator Works

Our "Am I Late Period Calculator" uses two key pieces of information to estimate your next period date and determine if it's late:

1. Last Period Start Date: The first day of your most recent menstrual period.
2. Average Cycle Length: The typical number of days from the start of one period to the start of the next. If you're unsure, tracking for a few months can give you a good average.

By adding your average cycle length to your last period start date, the calculator determines your expected period date. It then compares this date to today's date to tell you if your period is on time, expected soon, or how many days late it might be.

Common Reasons for a Late Period

While pregnancy is often the first thought when a period is late, many other factors can cause a delay. Here are some common reasons:

• Pregnancy: This is the most common reason for a missed or late period.
• Stress: High levels of physical or emotional stress can disrupt the hormones that regulate your cycle.
• Significant Weight Changes: Both significant weight gain and weight loss can affect your menstrual cycle.
• Excessive Exercise: Intense physical activity, especially in athletes, can sometimes lead to irregular or missed periods.
• Dietary Changes: Sudden or drastic changes in diet can impact your cycle.
• Medical Conditions: Conditions like Polycystic Ovary Syndrome (PCOS), thyroid disorders, or other hormonal imbalances can cause irregular periods.
• Medications: Certain medications, including some contraceptives, antidepressants, and blood pressure drugs, can affect your cycle.
• Travel or Schedule Changes: Disruptions to your routine, like jet lag or shift work, can sometimes throw off your cycle.
• Perimenopause: As women approach menopause, cycles often become irregular.

When to See a Doctor

While an occasional late period is usually nothing to worry about, it's a good idea to consult a healthcare professional if:

• You have missed three or more periods in a row.
• Your periods suddenly become very irregular after being regular.
• You experience severe pain, heavy bleeding, or unusual symptoms along with a late period.
• You suspect you might be pregnant and have a positive home pregnancy test.
• You are concerned about any changes in your menstrual cycle.

This calculator is a helpful tool for tracking and understanding your cycle, but it is not a substitute for professional medical advice. Always consult with a doctor for personalized guidance regarding your health.
