Why is my Period not coming?

It's easy to assume that you’ll get your period, but when that time of the month comes and you're surprisingly free of PMS and bleeding, you may start to wonder: am I pregnant?

First of all, don't panic! Your period disappearing for a month may be meaningless, although if you have 1 or 2 irregular menstrual cycles, it's definitely something to watch out for. 

My period is not here, what should I do? 

So, when do we talk about a delay? A healthy menstrual cycle is considered to be from 21 to 40 days. It depends on each woman and even on each cycle, because we are constantly changing, month by month.

Our first recommendation is that if you notice your period is late and you’ve had recent sexual relations, take a pregnancy test. It is not worth being in doubt or worried day after day. You can go to the pharmacy and buy a test, or even Amazon sells all kinds of pregnancy tests. 

Watch out! Some women may not be able to detect a pregnancy if just a few weeks have gone by. If the test is negative and you still don’t have your period, repeat the test or go to your gynecologist for a blood test.

Now, if you are definitely not pregnant and your period is still not coming, let's look at other causes. 

Significant weight loss

We know that excessive exercise, sudden weight changes or lack of weight can counteract hormone levels. One of these hormones is called leptin, which is produced in fat tissue. Excessive exercise and dramatic weight changes can decrease body fat, causing leptin and other hormones (such as estrogen) to decrease, contributing to irregular periods.

Talk to your doctor if you've had a large weight fluctuation recently so he or she can take this into account when dealing with your menstrual problems.

Excessive exercise

Rigorous exercise, such as training for a marathon or triathlon, can cause physical stress, which can lead to a hormonal imbalance. Women have a rather delicate hormonal system. Do you feel identified? Consult your doctor to discuss your case and get information on hypothalamic amenorrhea


Significant stress, such as a divorce, overwork or the death of a loved one, can disrupt hormonal balance, creating irregular periods. It works in the same way as in excessive exercise. Due to the stress we put on our bodies, the hypothalamus, pituitary and female gonads do not function properly.

Polycystic Ovary Syndrome (PCOS)

As we have discussed in other articles, PCOS can be one of the main causes of your period being irregular. PCOS is also characterized by ovaries with a polycystic morphology and high levels of androgens (male hormones). 

If you suspect PCOS, see a medical professional who has an overview of this metabolic condition. 

Contraceptive pills (COCs)

One of the side effects of a low estrogen contraceptive pill is a light period. We know that for many women, this is a welcome side effect. The same is true for methods such as hormonal IUDs, implants or injections, as many of these contain no estrogen at all, so it is normal not to have withdrawal bleeding using these methods. 

But if you've just stopped taking the pill, then consider: it can take one to three months for your hormonal system to return to its normal cycle. Still, pay attention to your cycles, as many times COCs have been given to cover hormonal imbalances and once you go off the pill these imbalances return. This can be seen very often in PCOS.

The thyroid gland

The thyroid gland, located in the neck, regulates metabolism, but also interacts with many other systems in the body to keep your metabolism running smoothly. 

If you have been diagnosed with any type of thyroid imbalance, either hypo or hyperthyroidism, this can have implications for your menstrual cycle and make it irregular. 

Premature Menopause

When women under the age of 40 have significant hormonal failure, they may go through premature menopause, also known as premature ovarian failure. Along with lack of menstruation, signs of this condition include hot flashes, night sweats and vaginal dryness.

See your gynecologist so that he or she can do a full hormonal study to discover the causes of your irregular menstrual cycles.
