It turns out stress doesn't cause delays, but these specific things do.
Stress is often called the universal cause of all problems. And if it really affects sexual desire, then it does not affect the regularity of your periods.
Cycle failure always causes some nervousness and suspicion of an unplanned pregnancy (if you have sex) or the onset of some kind of disease (if you do not). It has already been proven that the menstrual cycle is not affected by: stress, irregular meals, moving or physical activity. But there are many other reasons.
YOU ARE TRACKING YOUR CYCLES WRONGLY (IF YOU DO TRACK YOUR CYCLES AT ALL)
A normal menstrual cycle takes 21 to 40 days from the first day of the previous cycle to the first day of the next. If you don't follow it, there is a chance you will find it irregular. Most often this is what happens. Install a special application on your phone and get rid of a headache out of the blue.
YOU ARE TOO THIN
There is no specific minimum required BMI (body mass index) below which your period will definitely not come. Everything is individual. But a certain percentage of adipose tissue is necessary for this. From an evolutionary point of view, everything makes sense: if your body believes that famine times are in the yard and you can’t bear a child, it turns off the ability to reproduce until the situation is corrected.
Speaking of physical activity and leanness, as long as you don't do super-heavy activities like triathlon, your cycle is not in danger. Go to the gym for he alth.
YOU HAVE POLYCYSTOSIS OVARIAN
Polycystic Ovarian Syndrome (PCOS) is such a strange thing that causes the body to produce the right hormones in the wrong proportions. Doctors often observe that women with PCOS cycle irregularly or at large intervals of 6 to 8 weeks, and in some cases even up to a year. Get tested to rule out this diagnosis as a possible cause.
YOU JUST STARTED TAKING HORMONAL CONTRACEPTIVES
Regardless of the form (pills, injections, etc.), they all have a common property - your body needs time to adjust to the new hormonal background.
YOU MISS YOUR BIRTH PILLS
This is another common cause of missed periods. Make sure you take your tablets exactly as directed.
YOUR CYCLE IS SYNCHRONIZED WITH ANOTHER WOMAN
If you live in the same house with other women who are menstruating - your mother, sister, roommate, there is a very good chance that your cycles will start to adjust to each other. Scientists do not know why this happens, but it has happened to women at all times and on all continents. Can you imagine what it was like for the eastern rulers with their harems? Bang, and there's a "Closed for inventory" sign on the door.
YOU ARE TAKING CERTAIN MEDICINES
If you are on medication for depression, anxiety, or other mental disorders, your cycle may also be disrupted. The more medications you have been prescribed, the higher the chance. However, without consulting a doctor, you should not refuse to take medication. Moreover, in your case, hormonal contraceptives will be very appropriate, as they normalize the cycle. But, again - consult with experts.
YOU HAVE VAGINAL BLEEDING NOT RELATED TO MENSTRATION
Not all blood is a period. In very rare cases, bleeding can be caused by infectious lesions, growths, or foreign objects in the vagina. The best way to know if it's worth worrying about is to track your cycle. And if the blood came at the wrong time, see a doctor without delay.
