How long should we try to conceive naturally before seeing a GP or specialist?
Practical guidance on how long to try naturally before seeking NHS help or a fertility clinic, with clear timelines and what to expect at appointments.
Trying for a baby can feel straightforward for some couples and stubbornly slow for others. It helps to know the usual timelines, when to get medical help and what that help typically involves. Below is a friendly, practical guide to help you decide the right time to see a GP or a fertility specialist.
Basic timelines to use as a guide
- Under 35 years old: Try naturally for up to 12 months before seeing your GP if you have regular periods and no known fertility issues.
- 35–39 years old: Consider seeing your GP after 6 months of trying. Fertility does decline with age, so earlier assessment is sensible.
- 40 and over: Speak to your GP as soon as you decide to try. Fertility falls more quickly and a faster route to investigation and treatment is often recommended.
When to see a GP sooner
See a GP earlier than the timelines above if any of the following apply:
- You or your partner have a known fertility problem (for example, previous cancer treatment, known low sperm count, or PCOS).
- Your periods are very irregular or you don’t ovulate.
- You have had pelvic inflammatory disease, repeated miscarriages, endometriosis, or previous pelvic surgery.
- Your partner is male and has known fertility issues or symptoms such as testicular pain or swelling.
- You’re concerned about severe or unexplained pelvic pain.
- You want preconception advice because of a long-term condition or medication.
What your GP appointment will cover
Your GP will usually:
- Take a medical history for both partners and ask about menstrual cycles, sexual frequency and prior pregnancies.
- Check weight and general health, and advise on lifestyle changes that improve fertility.
- Offer initial investigations: blood tests (hormones), infection screening where appropriate, and a referral for a semen analysis for your partner.
- Refer you to NHS fertility services if initial tests suggest a problem or if you meet local criteria for specialist assessment.
What to expect from specialist (fertility clinic) investigation
If you’re referred to a fertility clinic, they’ll run a series of tests and then suggest a plan tailored to your situation. The aim is to find any issues that might be making it harder to get pregnant and to explain reasonable next steps.Common tests
- Ultrasound scans – These look at your ovaries and help estimate your ovarian reserve. That’s a way of saying roughly how many eggs you may have left.
- Fallopian tube tests – Clinics check that your tubes are open so an egg and sperm can meet. One common test is hysterosalpingography: a harmless dye is gently passed through the womb while an X‑ray shows whether it flows through the tubes.
- Hormone blood tests – Tests such as AMH, FSH and LH give information about your egg supply and whether you’re ovulating regularly. Your clinician will explain what each result means for you.
- Semen analysis – This looks at the man’s sperm count (how many), motility (how well they move) and morphology (shape). It’s a key part of fertility investigation.
Treatments they may discuss
After tests, the clinic will talk through options that match your results. These can include:
- Practical advice on timing intercourse and tracking ovulation
- Ovulation induction – medication to help you ovulate more reliably
- Intrauterine insemination (IUI) - sperm are placed directly into the womb around ovulation
- In vitro fertilisation (IVF) – eggs are collected and fertilised in a lab before placing an embryo into the womb
- Specialist procedures – for example, surgery if there’s a problem with the tubes
Your clinic will explain risks, success rates and costs, and help you choose what feels right.
Practical steps you can take while trying naturally
- Take 400 micrograms (mcg) of folic acid daily before conception and until 12 weeks pregnant (NHS guidance).
- Have regular sex during your fertile window - aim for every 1–2 days from about five days before ovulation to the day of ovulation.
- Track ovulation using cycle charts, ovulation predictor kits, or monitoring cervical mucus if that helps you time intercourse.
- Keep a healthy BMI - both underweight and overweight can affect fertility.
- Stop smoking and limit alcohol. Moderate caffeine intake is advised.
- Review medications with your GP to check for any that might affect fertility or pregnancy.
Understanding treatment timelines and NHS access
Access to NHS-funded fertility treatment varies by local commissioning groups. If you’re referred, expect some delay for assessments and treatment waiting lists. Private clinics offer faster access but come at a cost. Your GP can explain local criteria and likely waiting times.
When to seek urgent care
If you experience severe pelvic pain, heavy bleeding, fainting, or signs of possible ectopic pregnancy (sharp one-sided pain and vaginal bleeding), seek urgent medical attention or go to A&E.
Final practical tips
- Keep a simple record of your cycles and sexual activity - it helps at appointments.
- Talk openly with your partner about timing, emotions and next steps; fertility struggles can be stressful and it helps to be a team.
- If you’re feeling anxious or struggling emotionally, ask your GP about support services; counselling can be very helpful.
Deciding when to see a GP or a specialist depends on your age, medical history and how long you’ve been trying. Use the timelines above, be proactive about healthy habits, and don’t hesitate to ask your GP for a check-up - early assessment can speed up diagnosis and treatment when needed.
