Pregnancy preparation should ideally begin months — even a year — before you actually start trying, not after you get a positive test. Hormones don't change overnight, and eggs and sperm both need time to improve in quality. The core checklist: get your hormones evaluated (not just your periods tracked), check thyroid, blood sugar, and nutritional deficiencies, start folic acid, and address any existing condition like PCOS or irregular cycles early.
Get evaluated, not just "regular periods"
A period that arrives on schedule doesn't tell you everything about your hormonal readiness for pregnancy. Ask your gynaecologist to evaluate:
- Hormone levels, not only cycle regularity
- Thyroid function — an underactive or overactive thyroid can affect both conception and early pregnancy
- Blood sugar — insulin resistance affects egg quality even before it shows up as a diagnosis
- Nutritional deficiencies — particularly vitamin D and B12, and other commonly low levels
- Existing conditions — PCOS, irregular cycles, or painful periods are easier to manage when addressed before you're trying to conceive, not during
- CBC and prolactin — a routine blood count and prolactin level complete the basic tests
- Blood group and Rh factor — if you're Rh-negative and your partner is Rh-positive, the baby can be Rh-positive too, which can trigger an immune reaction in a later pregnancy. Knowing this before conceiving means an anti-D injection can be planned at the right points in pregnancy to prevent it
- Rubella immunity (Rubella IgG) — confirms whether you're protected against rubella, since catching it during pregnancy can affect the baby
- STI screening — your doctor may suggest screening for sexually transmitted infections based on your history, since untreated infections can affect fertility and pregnancy; this is a conversation with your doctor, not a test everyone needs by default
- Thalassemia carrier testing — worth doing before conception, since it can inform planning if both partners turn out to be carriers
- Expanded carrier screening (ECS) — a broader panel that checks for a wider range of inherited genetic conditions beyond thalassemia alone, worth discussing with your doctor especially if there's a family history of a genetic condition, consanguineous marriage, or you simply want a fuller picture before conceiving
- AMH and a baseline pelvic ultrasound — an additional fertility assessment worth discussing if you're over 35
Start folic acid before you're pregnant, not after
Folic acid (or folate) supports neural tube development in the earliest weeks of pregnancy — often before a missed period is even noticed. Start it as advised by your gynaecologist rather than waiting for a positive test, so the protection is already in place from conception.
Egg and sperm quality
Conception isn't only about timing ovulation — it depends on the health of the egg and sperm at a cellular level.
Egg quality is affected by age, insulin resistance, thyroid imbalance, low vitamin D, chronic stress, and poor sleep. Eggs provide all of the embryo's early energy supply, so poor egg quality raises the risk of failed fertilisation or poor embryo development. Support it with 7–8 hours of consistent sleep, stable blood sugar, correcting thyroid and vitamin D deficiencies, and — where your doctor advises — supplements like CoQ10 and folate.
Sperm quality is more than count — motility, shape, and DNA fragmentation all matter for embryo health. Stress, smoking, alcohol, obesity, overheating (laptops on the lap, tight clothing), and poor diet all increase oxidative stress, a type of cell damage that harms sperm DNA. Zinc, antioxidants, omega-3s, regular exercise, and cutting smoking and excess alcohol all support it.
Before asking "why am I not conceiving," ask "are our egg and sperm healthy enough to create a strong embryo?"
The lifestyle habits that support both
- Sleep — 7–8 hours nightly balances hormones and improves both egg and sperm quality
- Movement — about 150 minutes a week (walking, yoga, swimming, light jogging) supports a healthy weight and fertility
- Simple, nourishing food — eggs, fruits, green vegetables, dairy, nuts, seeds, whole grains, and fish
- Cut harmful habits early — reduce smoking, alcohol, and excess caffeine at least 3 months before trying
- Slow down mentally — time in nature, short breaks, a change of routine; lower stress supports better hormonal balance
- Stay emotionally connected with your partner — at least 30 minutes together, 2–3 days a week, matters as much as the physical checklist
- Try naturally, without pressure — during the fertile window, every day or alternate days is enough; keeping it gentle and unhurried matters more than a rigid schedule
- Simplify your skincare — switch to a basic, gentle routine and stop vitamin A–based products like retinol or adapalene while you're planning pregnancy
Frequently asked
How far in advance should we start preparing?
Months, ideally — the usual advice from fertility specialists is to start preparing at least 3 months before you plan to actively try, since eggs and sperm both take time to reflect lifestyle and nutritional changes.
Do we both need to get checked, or just the woman?
Both. Sperm quality is affected by many of the same lifestyle factors as egg quality, and issues on either side can affect conception — a preconception check is a couple's checklist, not just one partner's.
Should I start folic acid even before I'm actively trying?
Yes, if pregnancy is a near-term plan — neural tube development begins very early, often before you'd know you're pregnant, so starting folic acid ahead of conception (as advised by your gynaecologist) gives the earliest weeks the protection they need.
What if I already have PCOS or irregular cycles?
Address it before you start trying rather than after — these conditions are manageable, and getting your gynaecologist involved early gives more time to stabilise cycles and improve the odds once you do start trying.
Is expanded carrier screening different from thalassemia testing, and do I need both?
Thalassemia carrier testing checks for one specific condition; expanded carrier screening is a broader panel covering a wider range of inherited genetic conditions. Whether you need the expanded panel depends on your individual and family history — it's worth a direct conversation with your doctor rather than assuming either test alone is enough. If both partners turn out to be carriers of the same condition, your doctor can talk you through what that means for planning.
Why does my Rh factor matter before I even conceive?
If you're Rh-negative and your partner is Rh-positive, there's a chance your baby will be Rh-positive. If the baby's blood mixes with yours during pregnancy or delivery, your body can develop antibodies against Rh-positive blood — not usually a risk in a first pregnancy, but a concern in a later one. Knowing your Rh status before conceiving means your doctor can plan anti-D injections at the right points to prevent this.
Should we get screened for STIs before trying to conceive?
It depends on your history — this is a conversation to have directly with your doctor, not a test everyone needs by default. Some infections, if untreated, can affect fertility or be passed to the baby, so your doctor may suggest screening based on your or your partner's risk factors.
