Irregular or Delayed Periods and Infertility

What are irregular periods?

Females have periods in their menstrual cycles of 28-35 days. Experts term the gap as irregular periods when a woman does not have periods at the right time in a month. As a female, you can experience irregular periods in your reproductive age. Your delayed or irregular periods could be a result of hormonal imbalances. However, you should not have frequent irregularities or delays in your periods or at unexpected intervals. Sometimes, irregular periods can be one of the signs of infertility in females. You should visit a doctor and get the right treatment before it gets worse.  

What makes you have irregular or delayed periods?

Causes of period delays or irregularities differ from one female to another. Here are some possible causes that can make you prone to irregular periods:

  • Stress
  • Routine change 
  • Intensive exercises 
  • Weight gain or loss 
  • Eating disorders
  • High or low thyroid levels 
  • Hormonal imbalances caused by birth control pills, estrogen supplements, or patches 
  • Polycystic ovarian syndrome (PCOS)

Can your irregular periods cause infertility in you?

Often, a delayed or irregular period relates to infertility in women. Your age, hormonal imbalances, weight loss/gain, etc. can cause you to have irregularities or delays in your periods. You need to consult a fertility expert to identify the main reason. 

How can you know your periods are not regular?

You need to track your menstrual cycle. And for it, you can mark the date on which you bleed through your vagina. Vaginal bleeding is the beginning of your period in a menstrual cycle. Do date marking for a few months in a row. After 3-6 months, have a close look at the marked dates and find whether you had periods on a particular date or different ones. If the marked dates differ, you have irregular periods. A slight difference is okay, but there should be no big difference.
