Don’t just jump into conclusions and overthink why your period hasn’t arrived. A woman’s normal menstrual cycle will occur between 28 to 32 days. Aside from pregnancy and miscalculations, there are things that you might take into consideration when your period is late. Stated below are the reasons why Aunt Flo is arriving later than usual.

  1. Stress
  • Avoid stressing yourself once your period hasn’t arrived yet for stress may cause it to delay more. Stress causes a lot of discomfort in our body which results to headache, weight problems, skin issues, and menstrual delay. When a person is under a lot of stress, their body will go to a fight-or-flight response, wherein one’s system will decide which essential and nonessential functions should occur.
  1. Weight matters!
  • Losing or gaining weight can affect one’s hypothalamus (the gland responsible in regulating your menstrual cycle). If you are underweight or on a low-calorie diet, your body will not produce enough estrogen. However, if you are overweight, the body will produce too much estrogen. Estrogen is essential in regulating one’s menstrual period. Putting on a healthy weight will return your cycle in a normal state.
  1. Hormonal Imbalance
  • You might have a condition called Polycystic Ovarian Syndrome (PCOS) if your period is delayed. PCOS is a condition in which the female sex hormones are imbalance which causes several issues which includes a delay on one’s menstrual period.
  1.  You might be exercising TOO MUCH
  • Working out is good for you but overdoing it can delay your period. Over exercising will cause your body to produce not enough estrogen. As mentioned above, estrogen is essential in regulations one’s menstrual period.
  1. Medication
  • Taking any kind of medication (newly prescribed or a change of dosage) will cause menstrual delay.
  1. Thyroid disorder
  • Patients with hyperthyroidism (a condition where the thyroid gland over produces hormones) experience lighter and delayed period or vice versa. Some symptoms of hyperthyroidism are difficulty in sleeping, weight loss, weakness and irregular heartbeat.
  1. Change in schedule
  • Your body will take time to adapt with the changes in your usual routine.
  1. Sickness
  • When you are feeling a bit under the weather or in serious illness, your body will go on a fight-or-flight response wherein the body determines which function is important and not.
  1. Breastfeeding
  • Prolactin is the hormone responsible for milk production which will cause a delay in a woman’s ovulation. In short, NO OVULATION, NO PERIOD.
  1. Pre-menopause
  • When a woman is under her premenopausal stage, her body will tend to produce lesser estrogen, thus, making your period less and less frequent.
