Best tips to get pregnant fast and safely, backed by experts

TL;DR:

Take 400 mcg folic acid daily at least 1 month before trying.
Have sex every 1–2 days in the fertile window.
Stop smoking, avoid alcohol, and keep caffeine under 200 mg a day.
Use ovulation predictor kits if cycles vary.
See a clinician after 12 months of trying, or after 6 months if 35+.

What “best tips” really means

Conception depends on timing, egg and sperm health, and a few lifestyle habits. You can control many of these. Below is a simple, science-based plan that most couples can start today.

This guide is general information. It does not replace personal medical care.

Step 1: Get preconception basics in place

Take folic acid

Start a daily prenatal with at least 400 micrograms of folic acid. Begin at least 1 month before trying and keep taking it through the first trimester. This lowers the risk of neural tube defects. The CDC and ACOG advise this dose for most people. Some need more after a prior neural tube defect, under medical advice.

Review vaccines and immunity

Check rubella and varicella immunity before you try. MMR and varicella are live vaccines, not given in pregnancy. If you need them, get vaccinated and avoid pregnancy for 28 days after the shot. Your clinician can also advise on flu, Tdap, and COVID vaccines.

See your clinician if you can

Ask about long-term conditions, medicines, mental health, and genetic risks. A short visit now can save time later. ACOG’s prepregnancy guidance supports this approach.

Step 2: Time sex with the fertile window

Pregnancy is most likely from sex in the six days that end on ovulation day, with peak chance on the two days before ovulation. Intercourse every 1–2 days during this window gives the best results. These points come from ACOG and classic research in the New England Journal of Medicine.

Finding your window

Regular cycles, 24–35 days: Ovulation is usually 12–16 days before the next period.
Cycle clues: Rising clear stretchy cervical mucus often marks the window.
Tools: Ovulation predictor kits (OPKs) detect the LH surge 24–36 hours before ovulation.
Irregular cycles: Use OPKs for 2–3 months and have sex every 1–2 days when tests turn positive or mucus becomes clear and stretchy. Seek care if cycles are very long, very short, or absent.

Handy cycle-to-action table

If your cycle looks like…	Likely timing	What to do this month
28 days, fairly regular	Ovulation ~day 14	Sex every 1–2 days on days 10–16
32 days, fairly regular	Ovulation ~day 16	Sex every 1–2 days on days 12–18
Irregular, varies by >7 days	Unclear	Track with OPKs and mucus. Seek advice if ongoing

NHS suggests sex every 2–3 days if tracking is stressful.

Step 3: Build sperm- and egg-friendly habits

Quit smoking and vaping

Smoking harms egg quality, ovarian function, and sperm count. Stopping helps, and sperm measures can improve within months after quitting. ASRM and recent studies support quitting before trying.

Avoid alcohol while trying

There is no known safe amount when trying to conceive or in pregnancy. Stop alcohol now. CDC guidance is clear on this point.

Caffeine limits

Keep caffeine at or below 200 mg a day, about one 12-ounce coffee. EFSA-aligned reviews support this limit for those trying to conceive.

Aim for a healthy weight and active days

Extreme low or high BMI can affect ovulation and sperm quality. Choose regular meals, plants, lean protein, and daily movement. NHS and ASRM encourage healthy weight and activity while trying.

Heat and sperm

Very high heat can reduce sperm quality for weeks. Avoid hot tubs and very hot baths while trying. Evidence on underwear is mixed, so wear what is comfortable, but skip heat exposures.

Lubricants

Many household or common lubes can slow sperm. If you need one, pick an FDA-cleared “fertility-friendly” option or ask your clinician. Data suggest some lubes are less harmful, but no lube boosts fertility.

Step 4: Make sex simple, not stressful

Position, pillow tricks, or legs-up do not improve odds.
After sex, you can get up when you like.
Focus on timing, not choreography.

Step 5: Use smart tools, lightly

OPKs: Helpful for irregular cycles. Start testing a few days before you expect the surge.
Cycle apps: Good if they include your actual test results, not only averages.
Basal body temperature: Confirms ovulation after the fact. Use only if you like tracking.
ACOG notes that intercourse every 1–2 days in the window performs well even without heavy tracking.

When to get medical help

You are under 35 and have tried for 12 months with regular, well-timed sex.
You are 35 or older and have tried for 6 months.
Your periods are very irregular, very painful, or absent.
You have known conditions such as endometriosis, PCOS, fibroids, or prior pelvic infections.

Common questions

How long does it usually take?

Most couples conceive within 12 months with regular sex. Age matters, and fertility falls over time, which is normal biology. NHS provides this timeline.

How often should we have sex?

Every 1–2 days during the fertile window is ideal. Daily is fine if you prefer. Waiting many days can lower sperm counts. ACOG supports this schedule.

Do we need a special diet or supplements beyond folic acid?

A varied diet is enough for most people. Vitamin D or iodine may be advised in some regions. Ask your clinician based on local guidance and lab results.

Quick checklist

Prenatal with 400 mcg folic acid started.
Vaccines checked, MMR/varicella up to date before trying.
Smoking and vaping stopped. Alcohol avoided.
Caffeine at or below 200 mg daily.
Sex planned every 1–2 days in the fertile window.
OPKs ready if cycles vary.
Hot tubs skipped, stress managed, sleep steady.
Plan to seek help at 12 months, or 6 months if 35+.

Why it matters

Trying with a plan saves time and stress. A few habits and the right timing raise your odds each month. You also set up a safer pregnancy from day one.
