PCOS and Your Cycle
By the eva team · · 1 min read
PCOS stands for polycystic ovary syndrome. It is a hormone condition that can affect ovulation, which may lead to irregular periods or missed periods. Some people with PCOS may also notice acne, extra facial or body hair or changes in weight—but not everyone has the same symptoms. Learn what PCOS can look like, why it can affect your cycle and when it is worth getting checked.
1. What Is PCOS?
PCOS stands for polycystic ovary syndrome. It is a common hormone condition that can affect how the ovaries work. In many people, it can make ovulation happen less regularly, which may change the timing of periods.
2. How Can PCOS Affect Periods?
When ovulation does not happen regularly, periods may come less often, arrive unpredictably or be missed for long gaps. Some people with PCOS may have fewer periods in a year, while others may have irregular bleeding.
3. PCOS Can Affect More Than Your Period
Some people with PCOS may also notice acne, more facial or body hair than expected, scalp-hair thinning or weight changes. You do not need to have every symptom for PCOS to be considered, and having one of these symptoms does not automatically mean you have PCOS.
4. Irregular Periods Do Not Always Mean PCOS
Teen periods can also be irregular because of puberty, stress, intense exercise, thyroid problems, some medicines or other hormone changes. That is why PCOS cannot be diagnosed by guessing from one symptom or one irregular cycle.
5. When Should You Get Checked?
Talk to a trusted adult or healthcare professional if your periods stay very irregular, you go about three months without a period, or you have irregular periods along with significant acne, extra hair growth or other symptoms that concern you. A clinician may ask about your cycle, symptoms and sometimes recommend blood tests.
6. You Deserve Answers, Not Self-Blame
If you have PCOS, support is available. And if you do not, you still deserve help understanding your cycle. Tracking your periods and symptoms can make it easier to explain what is happening and get the right advice.
