Take a deep breath.

It's completely normal to experience a change in your period, but sometimes getting your period twice in one month can mean there is a bigger problem. 

The average cycle for a period is every 28 days but the range can be different for teens who just started menstruating, 21 to 45 days compared to an adult woman whose range can be anywhere between 21 to 35 days.

One main reason a woman can have two periods in one month is that her cycles are a lot shorter, which is very common in teen girls who have just started their period. Hormones in teen girls can change very often, leading them to have very long or short periods, and sometimes two periods in one month.

Below are some reasons why you might be experiencing two periods in one month:

Stress Can Affect Your Period 

Your stress level can really affect your overall health, but also your period.

If you're dealing with heavy amounts of stress, this can cause lack of sleep, irritability, or anxiety, which can then affect your cycle. 

Your Weight Can Change Your Menstrual Cycle

Dramatic weight gain or loss can affect your menstrual cycle whether you skip a month or get two in one month.   Two periods in one month isn't always a cause for concern, but if your cycle doesn't normalize by two or three months there might be an underlying health issue.

You Might Be Dealing With a Medical Condition 


Endometriosis occurs when tissue that would normally line the uterus begins to grow on the ovaries or fallopian tubes. Because the tissue cannot be released anywhere, it begins to irritate surrounding tissue. This can cause very painful periods and problems with fertility.

Endometriosis may also cause you to have heavy periods or two periods in one month. There are ways to treat endometriosis which can range from surgery to hormone treatments. Be sure to talk with your doctor to discover which method is best for you. 


Perimenopause is the stage leading up to menopause, which can happen anywhere from 10 years before a woman actually begins menopause. This can cause a change in hormones affecting your menstrual cycle. Women who are experiencing perimenopause may experience heavy or light periods and long or short periods.

Thyroid Problems

An underactive thyroid or Hypothyriodism is a condition that can affect your menstrual cycle.

Not ovulating is a result of progesterone deficiency, which is a result from Hypothyriodism. Reducing sex hormones and impairing the detoxification of estrogen are all results of a Thyroid problem. Woman dealing with an underactive Thyroid may be dealing with heavy or light periods and a change in their period cycle.
