Why has my menstrual cycle been irregular and delayed?

Question

Hello doctor,

My menstrual cycle has been irregular for the past two months. Two months ago, it arrived after 35 days instead of my usual 27 to 28 days, and last month, it came after 37 days. This month, it has not arrived yet, and it is now 36 days late. I am very concerned about this delay. Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

Possible reasons for your late period: A missed or delayed period for 36 days can result from various factors, including pregnancy, hormonal imbalances, stress, or underlying health conditions. Since your cycles have been getting longer over the past few months, it is important to explore the potential causes.

Pregnancy (the first thing to rule out):

If you have been sexually active, take a home pregnancy test as soon as possible.
If the result is negative, repeat the test in a few days or consider a blood test (hCG or human chorionic gonadotropin test) for confirmation.

Hormonal Imbalances:

Polycystic ovary syndrome (PCOS): It can lead to irregular, delayed, or skipped periods due to hormonal disruptions.
Thyroid disorders: Both hypothyroidism (occurs when the thyroid gland does not produce enough thyroid hormones) and hyperthyroidism (occurs when the thyroid gland produces too much thyroid hormone) can affect menstrual cycles.
High prolactin levels: Elevated prolactin can interfere with ovulation, leading to missed periods.

Stress and lifestyle factors

Emotional stress, travel, dietary changes, or excessive exercise can disrupt your cycle.
Weight fluctuations
Significant weight gain or loss can impact ovulation and delay menstruation.

Perimenopause (unlikely at a young age)

If you are in your late 30s or early 40s, irregular cycles could be an early sign of perimenopause (the transitional phase before menopause, during which a woman’s body gradually produces less estrogen and other reproductive hormones).

What you should do next

Take a pregnancy test immediately if sexually active.
If negative, consider consulting a doctor for blood tests (thyroid function, prolactin levels, and hormone panel).
Track your cycle and note any additional symptoms like acne, hair loss, or fatigue.
Manage stress and maintain a balanced diet and lifestyle to support a regular cycle.

I hope this helps.
