When is a period considered late?


At Cobb Women’s Health, we understand that menstrual health is a vital aspect of overall well-being for many women. A period is considered late when it does not start as expected based on your usual cycle length. Most individuals have a menstrual cycle that ranges from 21 to 35 days, with the average being about 28 days. If you typically experience a regular cycle and your period doesn’t begin within this timeframe, it may be considered late.

Several factors can affect the timing of your menstrual cycle, and occasional fluctuations are common. Stress, significant weight changes, excessive exercise, and lifestyle adjustments can all contribute to a late period. Hormonal imbalances, such as those caused by polycystic ovary syndrome (PCOS) or thyroid disorders, can also lead to irregular or late periods.

Certain medications and contraceptives can also affect menstrual regularity. For example, starting or stopping birth control pills may temporarily disrupt your cycle. Additionally, underlying health conditions like diabetes or celiac disease can influence menstrual timing by impacting hormonal balance or nutrient absorption.

We emphasize the importance of understanding your normal cycle pattern to determine if a period is late. We encourage tracking your menstrual cycles over several months, which can help identify what is typical for you. Our team is here to help you explore potential causes and receive appropriate guidance.

How many days late can a period be before I should worry?


Dr. Nandita Mainthia, MD, FACOG, and Dr. Hitendra Hansalia, MD, understand that menstrual health is a vital aspect of overall well-being for women. It’s important to recognize that menstrual cycles can vary significantly among individuals, and what’s typical for one person might not be for another.

A typical menstrual cycle lasts about 28 days, but it can vary between 21 and 35 days for adults and 21 to 45 days for teenagers. Generally, a period is considered late if it doesn’t begin five or more days after the expected start date. Occasional delays are common and can be caused by factors such as stress, weight fluctuations, exercise, illness, travel, or changes in routine. Hormonal imbalances, including conditions like polycystic ovary syndrome (PCOS) or thyroid issues, can also affect the timing of your cycle.

Pregnancy is a common reason for a late period. If you are sexually active, consider taking a pregnancy test if your period is late. If the test is negative and your period still doesn’t start, or if you experience symptoms like severe pain, heavy bleeding, or ongoing cycle irregularities, it may be time to seek medical advice.

We are here to help identify any underlying issues and offer personalized guidance to manage your menstrual health effectively. Your well-being is our top priority, and we are committed to supporting you with compassionate and knowledgeable care.

What should I do if my period is more than a week late?


We provide comprehensive care for women’s reproductive health, including concerns about menstrual irregularities. If your period is more than a week late, it can be a source of anxiety, but our team is here to support you in understanding the potential causes and finding solutions.

Pregnancy Considerations: If pregnancy is a possibility, taking a home pregnancy test is a good first step. These tests are most reliable after a missed period. If the test is positive or you’re unsure about the result, schedule an appointment with a healthcare provider for confirmation and further guidance.

Lifestyle and Health Factors: Stress, weight changes, diet, and exercise can affect your menstrual cycle. Our specialists can help evaluate these factors and their impact on your health. We can also check for conditions like PCOS or thyroid disorders, which may cause other symptoms such as fatigue or weight fluctuations.

Medication Impacts: Some medications, including hormonal contraceptives, can influence your cycle. If you think your medication is affecting your period, our providers can help explore alternatives or adjustments to your treatment.

When to Seek Further Evaluation: If your period doesn’t return within a few weeks or if you experience severe pain or unusual bleeding, it’s important to seek medical advice. We offer comprehensive evaluations to help identify any underlying issues.

Tracking Your Cycle: Keeping track of your cycle and any symptoms can help your healthcare provider pinpoint potential causes. This information helps tailor a care plan suited to your needs.

We are dedicated to addressing any ongoing concerns you may have about your menstrual health and ensuring you receive the support and care you need.

Can irregular periods cause a late cycle every month?


Irregular periods can lead to late cycles, as hormonal imbalances, particularly with estrogen and progesterone, disrupt the regularity of your menstrual cycle. Factors like stress, significant weight changes, excessive exercise, or conditions like polycystic ovary syndrome (PCOS) or thyroid disorders can contribute to irregular cycles. In certain life stages, such as puberty or perimenopause, irregular periods may be normal. However, if irregularities persist or are accompanied by other symptoms, it’s important to consult a healthcare provider for a thorough evaluation to identify any potential underlying issues.
