Intense exercise can cause irregular periods or cause your period to stop altogether. Often, this condition is associated with athletes who train for several hours daily. It’s most common in sports with weight constraints, like ballet and gymnastics.
What causes a period to come early?
Early periods often result from hormonal changes, especially during puberty and perimenopause. Many underlying medical conditions, including polycystic ovary syndrome (PCOS) and endometriosis, can also cause menstrual irregularities.
How does exercise affect periods?
Exercising too much can cause missed menstrual periods or make your periods stop entirely. Irregular or missed periods are more common in athletes and other women who train hard regularly.
Can exercise cause periods twice a month?
Weight — Stress, too much exercise, and weight changes can cause two periods in one month. Taking hormonal contraception — Bleeding between periods is common during the first several months of taking hormonal contraception. If it lasts longer, make sure to contact a health care provider.
