Why are my periods late?

In a certain situation, having a period within 35 days is normal and should not cause concern since women undergo a lot of transitionary changes within the monthly cycle.

Apart from being pregnant, many factors cause a period delay. Find doctor may help you identify the reason, based on your medical records and history. Here are some factors you may look forward to if your period is late.


Psychological factors are the most prominent factors that cause a period delay. During the monthly cycle, most women often experience mood changes that significantly impact their emotions. Emotional distress can affect the region of the brain that controls the pituitary gland, which regulates the hormones and is responsible for stimulating the reproductive process in the ovaries. Having extreme stress and anxiety can interrupt the production of hormones during ovulation and affect the menstrual cycle as a whole. Getting enough sleep and doing regular exercise may help you overcome your stress and boost your mood. You can reach a doctor or psychiatrist if you are having difficulties coping with your stress. They may prescribe you medications to stabilize your hormones.

Birth control

Birth control is intended to prevent unwanted or unplanned pregnancies. However, it can cause temporary hormonal imbalance and may disrupt your menstrual cycle. Birth control contains estrogen and progestin hormones to prevent ovulation and implantation on the wall of the uterus. Some birth control devices, such as IUDs, can also cause irregular or delayed periods. In general, birth control pills may induce hormonal changes in the body. You may experience irregular periods during the first few months after taking hormonal birth control pills, and it may take up to three months before your cycle comes back to normal after a person stops using birth control pills.

Polycystic ovary syndrome (PCOS)

Polycystic ovary syndrome is the most frequent condition that happens to a lot of women. Women with PCOS often have overgrown follicles inside their ovary, which has the potential to develop a cyst if the follicles don’t rupture to release an egg. Symptoms of PCOS such as weight gain, excessive growth of facial and body hair, and acne. Every month, each ovary produces an estimate of five follicles and the follicles have to compete to become the dominant and one of them would successfully release an egg. However, certain women who have had additional follicles experience a longer process than usual and are unable to produce an egg. No production of eggs means no period happens.

Unstable weight

Excessive weight loss or weight gain may cause a late period. People who practice vigorous exercise and a strict diet may also experience irregular periods. Staying healthy and monitoring your nutrient intake helps to stabilize a hormone and achieve your normal period flow. Be productive and engage in moderate physical activity that suits your body’s requirements.


The thyroid is responsible to produce thyroid hormone, which controls many activities in your body including your menstrual cycle. Thyroid disease happens if the thyroid hormone is expressed too much or too little, which is known as hyperthyroid or hypothyroid. Overexpression or underexpression of thyroid hormone may cause irregular periods. Patients may experience a condition called amenorrhea if they have thyroid disease, which may cause the periods to stop for several months or longer. They may have a possibility of getting early menopause if the thyroid disease is caused by an immune system that can affect the major parts of the organs in the body, including the ovary.


Some medications such as antidepressants or chemotherapy medicine can cause abnormal period flow. Besides that, prolonged usage of steroid medications may have consequences in many ways, including causing period irregularity.
