5 things that can cause an irregular cycle

One of the best things about Natural Cycles is that you get to know your body and your cycles. The more data and the longer you use Natural Cycles, the better the app gets to know you. We’re all a bit irregular but with Natural Cycles you will find out exactly how irregular your cycles are and how your cycles compare with other Cyclers. This is useful information for you to know because you will get a better overview over your cycles and mood, and at the same time you will know when your period will be due. If you want to plan a pregnancy in the future it might be even more useful to know more about your cycles and when you ovulate.

Except for the natural irregularities that every woman has, we’ve listed 5 things that may cause an irregular cycle:

 

1. Stressful / irregular lifestyle

Hard training, significant weight loss or weight gain, stress and traveling can result in irregular periods.

 

2. PCOS

Around 5-10% of all women experience irregular periods due to polycystic ovarian syndrome. In women with PCOS, the ovaries make more androgens than normal, which affects the development and release of eggs during ovulation. Therefore, women with PCOS often experience anovulatory cycles where ovulation does not occur. This means that the hormone progesterone is not made and without progesterone, a woman’s menstrual cycle is irregular or absent. Read more about how you can use Natural Cycles with PCOS here.

 

 

3. After hormonal contraception.

If you have recently been on hormonal contraception, it is likely that your cycle will be out of balance and irregular. It is very individual for how long your cycles will be irregular but some of our Cyclers have experienced irregular cycles up to a year.

 

 

4. After pregnancy

Even though pregnancy isn’t the same as being on hormonal contraception, the hormones from the pregnancy have a similar effect on your cycle to start, it can be irregular a while before it stabilizes.

 

 

5. Endometriosis

Endometriosis is where the lining of blood is also found outside your uterus. Areas that are most commonly involved are your ovaries, bowel or the tissue lining your pelvis. 10% of women worldwide have endometriosis – that’s 176 million worldwide. What it can cause  is irregular and very painful periods.
