If you are wondering about getting pregnant naturally with PCOS, the good news is that PCOS, also called Polyendocrine Metabolic Ovarian Syndrome (PMOS), does not mean you cannot become pregnant. Many women with PCOS conceive naturally, while others may need medical support to improve ovulation.
PCOS/PMOS can affect fertility mainly because it may cause irregular or absent ovulation. Understanding your ovulation pattern can help your gynecologist decide whether you need treatment and which approach may suit you best.

What Is the Connection Between PCOS/PMOS and Pregnancy?
PCOS/PMOS can affect your menstrual cycle and ovulation. When you do not ovulate regularly, you have fewer opportunities to conceive during each menstrual cycle.
However, having PCOS/PMOS does not automatically mean infertility. Some women continue to ovulate and become pregnant without fertility treatment, while others may need medicines or assisted reproductive treatment.
International guidelines also reassure women with PCOS that pregnancy can often occur naturally or with appropriate fertility treatment.
Can You Get Pregnant Naturally With PCOS?
Yes, getting pregnant naturally with PCOS is possible.
Your chances of natural conception depend on several factors, including whether you ovulate regularly, your age, your overall reproductive health, and whether you or your partner have other fertility concerns.
If you have irregular periods but still ovulate occasionally, you may become pregnant naturally. However, irregular ovulation can make it harder to predict your fertile days and may increase the time it takes to conceive.
How Does PCOS Affect Ovulation?
Ovulation occurs when an ovary releases an egg. PCOS/PMOS can interfere with the hormonal signals that control this process.
As a result, some women may:
- Ovulate less frequently than usual
- Have irregular menstrual cycles
- Skip periods for several weeks or months
- Have difficulty predicting their fertile window
- Need treatment to help trigger regular ovulation
Not every woman with PCOS has the same ovulation pattern. Your doctor can assess your menstrual history and, when appropriate, use tests or ultrasound to understand your ovulation pattern.
How Do I Know If I Am Ovulating With PCOS?
Irregular periods can make ovulation difficult to predict, but they do not always mean that you never ovulate.
Your doctor may assess ovulation using your menstrual history, blood tests, and ultrasound when appropriate. Some women also track ovulation at home, although irregular cycles can make home ovulation prediction less straightforward.
If you are trying to conceive, identifying whether and when you ovulate can help your doctor choose the right fertility approach.
What Can Improve Your Chances of Getting Pregnant With PCOS?
Several factors can support fertility and improve your overall reproductive health.
Maintain a healthy lifestyle
Regular physical activity and a balanced diet can support metabolic health and overall wellbeing. If you have excess weight, even modest weight loss may improve metabolic health and, in some women, help improve menstrual regularity and ovulation.
However, PCOS/PMOS can affect women at any body weight, so fertility care should focus on your overall health rather than weight alone.
Track your menstrual cycle
Keeping track of your periods can help you and your doctor understand how regular your cycles are. If your cycles remain irregular, your doctor can assess whether you are ovulating regularly.
Take recommended prenatal supplements
If you are planning pregnancy, discuss prenatal vitamins and folic acid with your doctor. Your doctor can recommend the appropriate dose based on your individual health and nutritional needs.
Manage existing health concerns
PCOS/PMOS can occur alongside metabolic concerns such as insulin resistance, high blood pressure, or abnormal blood sugar levels. Managing these concerns before pregnancy can support healthier pregnancy planning.
When Should You See a Fertility Specialist?
You may benefit from an earlier fertility evaluation if:
- Your periods are very irregular or absent
- You know that you do not ovulate regularly
- You have been trying to conceive without success
- You are concerned about your fertility because of your age or medical history
- You have PCOS/PMOS and want to plan a pregnancy
You do not always need to wait 12 months before seeking medical advice. Very irregular or absent periods can indicate irregular ovulation, so speaking with a gynecologist earlier may help identify the problem and avoid unnecessary delays.
What Fertility Treatments Can Help With PCOS/PMOS?
If PCOS/PMOS affects your ovulation, your doctor may recommend treatment to help you ovulate.
Ovulation-inducing medicines
For women with PCOS/PMOS who have difficulty conceiving because they do not ovulate regularly, doctors may recommend medicines that help induce ovulation. Current international guidance recommends letrozole as the preferred first-line ovulation-induction medicine when there are no other infertility factors.
Your doctor should decide whether this treatment is appropriate for you after evaluating your health and fertility.
Metformin
Doctors may recommend metformin for some women with PCOS/PMOS, particularly when metabolic concerns are present. In certain fertility situations, doctors may also consider it as part of ovulation treatment.
Metformin does not work as a fertility treatment for every woman, so your doctor should determine whether it suits your individual situation.
IUI
If ovulation treatment does not result in pregnancy or other fertility factors are present, your doctor may consider intrauterine insemination (IUI).
IVF
Some women with PCOS/PMOS may need in vitro fertilisation (IVF), particularly when other fertility factors exist or when simpler treatments have not worked.
Having PCOS/PMOS does not automatically mean that you need IVF.
Does PCOS Increase Pregnancy Risks?
PCOS/PMOS can increase the risk of certain pregnancy complications, so doctors may recommend appropriate monitoring during pregnancy.
Depending on your individual health, your doctor may monitor factors such as blood pressure, blood sugar, and other pregnancy-related risks.
This does not mean that every woman with PCOS will develop complications. Proper preconception planning and regular antenatal care can help your healthcare team identify and manage potential risks.
What Should I Do Before Trying to Get Pregnant With PCOS?
If you are planning pregnancy, speak with your gynecologist before you start trying. Your doctor may review:
- Your menstrual cycle and ovulation pattern
- Your current medicines and supplements
- Your blood pressure and metabolic health
- Your blood sugar levels when appropriate
- Your vaccination and preconception needs
- Other factors that may affect fertility
This preconception assessment can help you address health concerns before pregnancy and create an appropriate fertility plan.
Can PCOS Be Treated Before Pregnancy?
Yes. Treatment depends on your symptoms, health, and pregnancy plans.
If you are not currently trying to conceive, your doctor may focus on managing irregular periods, acne, excess hair growth, or metabolic concerns. If you want to become pregnant, the treatment plan will focus more on ovulation and fertility.
Do not stop or start medicines on your own when planning pregnancy. Discuss your medicines with your gynecologist so they can make any necessary changes safely.
PCOS/PMOS and Pregnancy: The Bottom Line
PCOS/PMOS does not mean you cannot get pregnant. Many women with PCOS conceive naturally, while others need treatment to improve ovulation or address additional fertility factors.
If you have irregular periods or have been trying to conceive, do not rely only on symptoms to determine whether you are ovulating. A gynecologist or fertility specialist can evaluate your menstrual pattern, ovulation, and overall reproductive health and recommend the right approach for you.
