How to Get Pregnant Faster: What the Evidence Actually Shows
Most healthy couples under 35 conceive within 6 months of trying. These are the steps with the strongest evidence.
1. Know Your Fertile Window
The fertile window is the 5 days before ovulation plus ovulation day — 6 days total. The most fertile days are the 2 days immediately before ovulation and the day of ovulation itself. An egg survives only 12–24 hours after release; sperm survive 3–5 days.
2. Track Ovulation With LH Test Kits
LH ovulation test kits (OPKs) detect the LH surge 24–36 hours before ovulation. Start testing on day 10 of a 28-day cycle (earlier for shorter cycles). A positive result means ovulation is approaching — have intercourse that day and the next.
Types: Strip tests (₹150–₹400 for 10 strips) are cheapest. Digital tests (₹800–₹1,500) give a clear peak reading. Dual-hormone monitors add estrogen tracking for 4+ fertile days of warning.
3. Have Sex Every 1–2 Days During the Fertile Window
ASRM 2023: intercourse every 1–2 days during the fertile window is optimal. Daily sex does not reduce sperm quality in men with normal counts. Waiting more than 5 days may reduce quality slightly.
4. Start Folic Acid Now — Before You Conceive
400–800mcg daily, ideally 3 months before trying. Reduces neural tube defect risk (spina bifida) by 70%. The neural tube forms in the first 4 weeks — before most women know they are pregnant. Women with a history of NTD pregnancy need 5mg prescription dose.
5. Follow a Mediterranean Diet
The Mediterranean diet pattern is associated with 40% higher IVF live birth rates in women under 35 (ESHRE cohort study 2018). For natural conception, it supports egg quality and hormone balance. Key elements: abundant vegetables, legumes, whole grains, oily fish 2–3×/week, olive oil, nuts, full-fat dairy. Limit: processed foods, refined carbohydrates, excess caffeine (under 200mg/day), alcohol.
6. Reach a Healthy Weight
Both underweight (BMI <18.5) and overweight (BMI >27) reduce fertility. In overweight women with PCOS, a 5% weight reduction restores ovulation in 55% of cases without any medication. Underweight women may experience hypothalamic amenorrhoea — ovulation stops when body fat is too low.
7. Quit Smoking — Both Partners
Smoking halves fertility in women (accelerates ovarian reserve decline, doubles ectopic pregnancy risk) and reduces sperm count and motility by 15–20% in men while significantly increasing sperm DNA damage. This is the highest single-impact lifestyle change available to both partners.
8. Correct Vitamin D Deficiency
Vitamin D deficiency (<20 ng/mL) is associated with significantly lower IVF success rates. The majority of Indians are Vitamin D deficient. A blood test and, if low, supplementation of 1000–2000 IU daily, is a simple evidence-based step.
9. Reduce Stress Intelligently
Severe chronic stress can suppress ovulation through the HPO axis. However, normal life stress has not been shown to cause infertility. Effective evidence-based approaches: MBSR (mindfulness-based stress reduction), yoga, peer support groups. Do not avoid holidays, social activities, or sex outside the fertile window in the name of "optimisation" — the evidence does not support this.
10. Know When to Seek Help
- Under 35: After 12 months of trying
- Age 35–39: After 6 months
- Age 40+: Immediately — ideally before starting to try
- Any age: If cycles are irregular, PCOS/endometriosis is known, previous STIs, or partner has known fertility issues
A basic workup — AMH, day 3 bloods, pelvic ultrasound, semen analysis — takes one cycle and answers most questions.

Frequently Asked Questions
What is the fastest way to get pregnant?▾
The most impactful steps: (1) use LH ovulation test kits to identify your fertile window, (2) have intercourse every 1–2 days in the 5 days before ovulation, (3) start folic acid 400mcg daily, (4) both partners quit smoking. These changes can meaningfully improve your per-cycle conception chance. Seek evaluation after 12 months under 35 or 6 months over 35.
What time of day should you have sex to conceive?▾
There is no evidence that time of day significantly affects conception rates. What matters far more is having intercourse on the correct days of the cycle. Focus on timing relative to ovulation, not time of day.
Does lying down after sex help you get pregnant?▾
Evidence is weak. Sperm enter the cervix within seconds of ejaculation and gravity plays no role thereafter. There is no robust evidence that lying still after intercourse improves natural conception rates. You do not need to rest or change position after sex.
Can stress stop you from getting pregnant?▾
Severe chronic stress can disrupt the hormonal axis and suppress ovulation in some women. However, normal everyday stress has not been shown to cause infertility. If you are experiencing significant anxiety about conception, mindfulness, CBT, and peer support groups are evidence-supported approaches — both for your wellbeing and potentially for fertility.
