Stages of the Fertility Journey
Stages of the Fertility Journey
The path to conception involves distinct stages, each with its own focus, challenges, and opportunities for optimisation. Whether you are just beginning to think about starting a family or have been trying for some time, understanding each stage helps you take a proactive, informed approach.
Stage 1: Preconception Planning
The preconception period — ideally 3–6 months before trying to conceive — is one of the most impactful windows for improving fertility outcomes. Both partners' health matters: egg quality, sperm quality, hormonal balance, and uterine health are all influenced by lifestyle and nutritional status in the months before conception.
Key actions at this stage
- Start methylfolate (both partners benefit from folate)
- Test and optimise vitamin D levels
- Begin CoQ10 supplementation (particularly if over 35)
- Review diet: adopt a Mediterranean-style eating pattern
- Reduce alcohol, caffeine (under 200mg daily), and smoking
- Achieve a healthy weight if possible
- Track your cycle to understand your fertile window
- Book a preconception GP appointment to review medications and check for conditions that may affect fertility
Stage 2: Actively Trying to Conceive
Once you begin trying to conceive, timing intercourse around the fertile window maximises the chance of conception. The fertile window is the 5 days before ovulation and the day of ovulation itself — sperm can survive in the reproductive tract for up to 5 days, while an egg is viable for only 12–24 hours after release.
Identifying the fertile window
- Ovulation predictor kits (OPKs): Detect the LH surge 24–36 hours before ovulation. Reliable and easy to use.
- Cervical mucus monitoring: Egg-white cervical mucus indicates peak fertility.
- Basal body temperature (BBT) tracking: Confirms ovulation has occurred (temperature rises after ovulation). Best used in combination with OPKs.
- Cycle tracking apps: Useful for identifying patterns, but predictions are based on averages and may not reflect your individual cycle.
How often to have sex
Every 1–2 days throughout the fertile window maximises the chance of conception. Daily sex is not necessary and may increase stress. Sperm quality is generally best with ejaculation every 2–3 days.
Stage 3: The Two-Week Wait (2WW)
The two-week wait is the period between ovulation and the expected date of your next period — the time during which implantation may occur and a pregnancy test becomes meaningful. It is often the most emotionally challenging part of the fertility journey.
What is happening during the 2WW
- Days 1–5 post-ovulation: The fertilised egg (if conception occurred) travels down the fallopian tube
- Days 6–10: Implantation occurs (if it occurs)
- Days 10–14: hCG begins to rise if implantation was successful
Implantation symptoms
Some women experience light spotting (implantation bleeding), mild cramping, or breast tenderness around days 6–10 post-ovulation. These symptoms are not reliable indicators of pregnancy — many women have no symptoms at all.
When to test
A pregnancy test is most accurate from the first day of a missed period. Testing earlier may give a false negative. Early response tests can detect hCG from around 10–12 days post-ovulation.
Stage 4: When Conception Takes Longer
It is normal for conception to take time. In couples under 35 with no known fertility issues, approximately 84% will conceive within 12 months. After 12 months of trying (or 6 months if over 35), a fertility assessment is recommended.
Fertility investigations
A standard fertility workup includes:
- For women: Day 2–3 hormone panel (FSH, LH, oestradiol, AMH), day 21 progesterone, thyroid function, pelvic ultrasound (antral follicle count), and a tubal patency test (HSG or HyCoSy) if indicated.
- For men: Semen analysis (count, motility, morphology, DNA fragmentation).
Assisted reproduction options
- Ovulation induction: Medication (clomifene, letrozole) to stimulate ovulation in women who are not ovulating regularly.
- IUI (intrauterine insemination): Sperm is placed directly into the uterus around ovulation.
- IVF (in vitro fertilisation): Eggs are retrieved, fertilised in the laboratory, and embryos are transferred to the uterus.
- ICSI (intracytoplasmic sperm injection): A single sperm is injected directly into an egg — used for male factor infertility.
