The Pre-Pregnancy Health Check: The Six Months Before You Try
The health of both parents in the six months before conception influences the pregnancy more than any intervention during it. A pre-pregnancy check identifies conditions that need optimising, updates vaccinations that cannot be given during pregnancy, adjusts medications that need changing, and sets a baseline against which pregnancy changes can be measured. Most Indian couples skip this entirely and start pre-natal care after conception.
What to check in the woman
- Category: Chronic conditions · Test / assessment: Diabetes, thyroid, hypertension review · Why: Must be well-controlled before conception
- Category: Immunity · Test / assessment: Rubella, varicella, hepatitis B · Why: Cannot vaccinate during pregnancy
- Category: Nutritional · Test / assessment: Ferritin, B12, vitamin D · Why: Common Indian deficiencies impact pregnancy
- Category: Iron · Test / assessment: Hb + ferritin · Why: Pre-pregnancy iron reserves matter for third trimester
- Category: Thyroid · Test / assessment: TSH · Why: Hypothyroidism affects fetal brain development
- Category: Blood group · Test / assessment: ABO + Rh · Why: Rh-negative women need anti-D during pregnancy
- Category: Genetic screening · Test / assessment: Thalassaemia carrier, others · Why: If either partner from at-risk community
- Category: Sexual health · Test / assessment: HIV, syphilis, hepatitis B/C · Why: Standard antenatal panel, better done now
- Category: Dental · Test / assessment: Full exam and clean · Why: Gum disease linked to pre-term birth
What to check in the man
- General health — chronic conditions, smoking, alcohol use.
- Any medications that affect fertility or fetal development.
- Semen analysis if any concern (or if pregnancy hasn't happened in 6+ months).
- Genetic screening if family history or ethnicity concerns (thalassaemia).
- HIV, syphilis, hepatitis B/C.
- BMI — obesity in both partners affects fertility.
Medication review — the specific pregnancy category question
Some common medicines are unsafe or need adjustment before pregnancy:
- ACE inhibitors, ARBs — teratogenic; switch before conception.
- Warfarin — teratogenic; switch to heparin.
- Isotretinoin — must stop months before.
- Some anti-epileptics — dose or drug change.
- Some antibiotics for chronic conditions — review.
- Herbal supplements — many not studied for pregnancy safety.
The specific ask: your gynaecologist and any specialist you see for chronic conditions should coordinate on medication review at least 3-6 months before you try to conceive.
Vaccinations to update
- MMR (measles, mumps, rubella) — no pregnancy for 1 month after.
- Varicella if not immune — no pregnancy for 1 month after.
- Hepatitis B if not vaccinated.
- Tdap booster.
- Annual flu.
- COVID-19 vaccination up to date.
- HPV if under 26 and not previously.
Lifestyle optimisation
- Folic acid 400-800 mcg daily, ideally 3 months before conception (5 mg if high risk).
- Stop smoking — both parents.
- Reduce alcohol to zero for planning female; moderate for male.
- Weight optimisation if BMI extreme.
- Aerobic exercise habits established.
- Sleep improved.
- Stress management approach in place.
Timing considerations
- Age matters — female fertility declines after 35, sharply after 40.
- Male fertility also declines with age but more gradually.
- Time to conception averages 6-12 months for most couples.
- If over 35 and not pregnant after 6 months, or under 35 and after 12 months, consider fertility evaluation.
The record to build
- Full baseline health status of both partners.
- Genetic risk assessment.
- Immunisation status.
- Medications reviewed and adjusted.
- Lifestyle interventions started.
- Timeline of the process from planning to conception.
A pregnancy that begins well-prepared is a substantially different pregnancy from one where problems are discovered at the first antenatal visit. The specific work done in the six months before is what makes the difference.
