If you’ve been asking yourself, “Why am I not getting pregnant?”, you’re not alone. Millions of couples experience delays in conceiving, even when they are trying consistently.
While some people become pregnant within a few months, others may take longer due to age, lifestyle, medical conditions, or fertility issues affecting either partner.
The good news is that many causes of infertility are treatable.
Basically, understanding what might be affecting your fertility is the first step towards finding the right solution.
In this article, we’ll explain the most common reasons pregnancy may not happen, when you should seek medical help, and what you can do to improve your chances of conception.
How Long Does It Normally Take To Get Pregnant?
For healthy couples:
About 80% conceive within one year.
Around 90% conceive within two years.
Doctors generally recommend seeking medical advice if:
- You’re under 35 and have tried for one year
- You’re 35 or older and have tried for six months
- You’re over 40 and trying to conceive
- You’ve had repeated miscarriages
- You have irregular periods or known reproductive conditions.
1. You’re Not Ovulating Regularly
Ovulation is necessary for pregnancy. Without releasing an egg, fertilisation cannot occur.
Signs include:
- Irregular periods
- Absent periods
- Unpredictable menstrual cycles
Possible causes:
- PCOS
- Thyroid disorders
- Hormonal imbalance
- Excessive exercise
- Stress
For instance, a 2023 review published in the Journal of Clinical Medicine reported that ovulation disorders account for about 25% of infertility cases among couples struggling to conceive. The review also found that hormonal imbalances, insulin resistance, diet, and certain lifestyle factors can all contribute to ovulatory infertility (1).
2. You’re Having Sex At The Wrong Time
Many couples simply miss the fertile window.
The best time is:
- Five days before ovulation
- Ovulation day
- One day after ovulation
Ovulation tracking apps, cervical mucus monitoring, and ovulation predictor kits can help identify this window.
According to a research, clinical fertility guidelines consistently show that the highest chance of conception occurs when intercourse takes place during the five days before ovulation and on the day of ovulation, as sperm can survive in the female reproductive tract for several days while the egg remains viable for only about 12–24 hours (2).
3. Age Is Affecting Fertility
Female fertility gradually declines after age 30 and more rapidly after 35 due to fewer and lower-quality eggs. Male fertility can also decrease with age, though usually more gradually.
Also, research has shown that the age-related decline in fertility is largely due to increasing chromosomal abnormalities in eggs. These abnormalities make fertilisation less likely and increase the risk of miscarriage (3).
4. Polycystic Ovary Syndrome (PCOS)
PCOS is one of the most common causes of infertility.
Symptoms:
- Irregular periods
- Acne
- Excess facial hair
- Weight gain
- Difficulty conceiving
Studies consistently identify PCOS as one of the most common causes of ovulation disorders. Women with PCOS often experience irregular ovulation due to hormonal imbalances and insulin resistance, making conception more difficult (4).
5. Blocked Fallopian Tubes
Furthermore, every woman trying to conceive should know that blocked tubes prevent sperm from meeting the egg.
Common causes include:
- Untreated sexually transmitted infections
- Pelvic inflammatory disease
- Previous surgery
- Endometriosis
Medical research shows that tubal damage is commonly linked to untreated pelvic infections, previous pelvic surgery, or endometriosis. Early diagnosis and treatment can significantly improve fertility outcomes (5).
6. Endometriosis
This condition occurs when tissue similar to the uterine lining grows outside the uterus, potentially causing pain and fertility challenges.
Symptoms include:
- Painful periods
- Painful intercourse
- Chronic pelvic pain
- Infertility
Researchers believe endometriosis may reduce fertility by causing inflammation, pelvic adhesions, ovarian damage, and distortion of reproductive anatomy, all of which may interfere with fertilisation and implantation (6).
7. Male Fertility Problems
Pregnancy depends on both partners. Around 30–50% of infertility cases involve male factors.
Possible causes:
- Low sperm count
- Poor sperm movement
- Abnormal sperm shape
- Varicocele
- Smoking
- Alcohol
- Obesity
- Infections
Both partners should be evaluated when pregnancy is delayed.
Why is this necessary?
A 2022 scoping review that analysed 60 published studies found that male infertility is influenced by a combination of biological, genetic, environmental, and lifestyle factors. Low sperm count, poor sperm movement, and abnormal sperm shape remain among the leading contributors to male infertility (7).
According to the World Health Organization, male factors contribute to approximately half of infertility cases, highlighting the importance of evaluating both partners during fertility investigations (8). This means it is 50-50.
8. Being Above or Below Body Mass Index
Body weight influences hormone production and ovulation. Achieving a healthy weight can improve fertility.
Scientific reviews suggest that obesity and being significantly underweight can disrupt ovulation through hormonal changes. Weight management has been shown to improve ovulation and pregnancy outcomes in many women (9).
9. Smoking, Alcohol And Drug Use
Smoking damages eggs and sperm. Heavy alcohol use and recreational drugs can also reduce fertility.
Research indicates that smoking damages egg quality, reduces ovarian reserve, and negatively affects sperm quality. Excessive alcohol consumption and recreational drug use have also been associated with reduced fertility in both male and female (10).
10. Chronic Stress
Stress alone doesn’t usually cause infertility but can disrupt hormones, ovulation, and healthy routines.

Researchers suggest that chronic stress can alter hormone regulation, disrupt ovulation in some women, and contribute to unhealthy lifestyle behaviours that indirectly reduce fertility (11).
11. Medical Conditions
Health issues that may affect fertility include:
- Diabetes
- Thyroid disease
- Autoimmune disorders
- Untreated infections
- Hormonal disorders
Medical studies have shown that thyroid disorders, diabetes, autoimmune diseases, and hormonal conditions can impair ovulation, implantation, or sperm production if left untreated (12).
12. Certain Medications
Some medications may interfere with fertility, including specific chemotherapy drugs, long-term steroids, and others. Always consult your healthcare provider before stopping prescribed medicines.
13. Previous STIs
Also, untreated sexually transmitted infections can lead to scarring and fertility problems.
Research has consistently found that untreated infections can lead to pelvic inflammatory disease, scarring of the fallopian tubes, and reduced fertility in women. In men, certain infections may impair sperm production and quality (13).
14. Unexplained Infertility
Sometimes no specific cause is found despite normal test results. Many couples with unexplained infertility still conceive naturally or with treatment.
Studies estimate that 10–20% of infertility cases are classified as unexplained infertility, meaning current medical tests cannot identify a specific cause even though conception has not occurred (13).
Where there is an unexplained infertility, partners are often advised to:
Optimise Your Lifestyle
Even without a known cause, improving overall health can increase the chances of conception. Both partners should:
- Maintain a healthy weight.
- Eat a balanced, nutrient-rich diet.
- Exercise regularly without overtraining.
- Avoid smoking and recreational drugs.
- Limit alcohol intake.
- Get enough sleep.
- Manage stress through healthy coping strategies.
- Time intercourse correctly.
15. You’re Simply Still Within The Normal Time Frame
It is normal for healthy couples to take several months to conceive. Patience and healthy lifestyle habits remain important.
How to Improve Your Chances of Getting Pregnant
- Track ovulation accurately.
- Maintain a healthy weight.
- Eat a balanced diet rich in fruits, vegetables, whole grains, and lean proteins.
- Exercise regularly without overtraining.
- Stop smoking.
- Limit alcohol.
- Take folic acid before conception.
- Get adequate sleep.
- Manage stress.
- Have regular intercourse every two to three days during the fertile window.
- Encourage your partner to adopt healthy lifestyle habits too.
- When Should You See a Fertility Specialist?
Consult a fertility specialist if:
- You’re under 35 and have tried for 12 months
- You’re 35 or older and have tried for six months
- Your periods are irregular or absent
- You’ve had repeated miscarriages
- Your partner has known fertility issues
- You’ve been diagnosed with PCOS, endometriosis, or blocked tubes
Early assessment can improve treatment options and outcomes.

Frequently Asked Questions On Why A Female Is Not Getting Pregnant
Why am I not getting pregnant even though I ovulate?
Ovulation is only one part of conception. Factors such as sperm quality, blocked fallopian tubes, endometriosis, age, or hormonal issues may also affect fertility.
Can stress stop me from getting pregnant?
Stress alone is unlikely to cause infertility, but it may affect ovulation and healthy habits that support conception.
Can a man be the reason pregnancy isn’t happening?
Yes. Male fertility factors contribute to around one-third to one-half of infertility cases, which is why both partners should be evaluated.
How long should we try before seeing a doctor?
Furthermore, if you’re under 35, seek advice after one year of trying. If you’re 35 or older, see a healthcare provider after six months.
Can lifestyle changes improve fertility?
For many people, maintaining a healthy weight, stopping smoking, limiting alcohol, managing stress, and eating a nutritious diet can improve fertility.
