Preparing for conception starts well before you stop using birth control. The steps you take in the three to six months leading up to a pregnancy can influence how quickly you conceive, how healthy the early weeks of development are, and how smoothly the pregnancy progresses. Both partners play a role, and most of the preparation comes down to practical changes you can start today.
Start Folic Acid at Least One Month Early
Folic acid is the single most important supplement for preconception. It prevents neural tube defects, which are serious birth defects of the brain and spine that develop in the first few weeks of pregnancy, often before you even know you’re pregnant. The CDC recommends 400 mcg of folic acid every day for all women who could become pregnant, starting at least one month before conception. If you’ve had a previous pregnancy affected by a neural tube defect, the recommended dose jumps to 4,000 mcg daily, which requires a prescription-strength supplement.
A standard prenatal vitamin covers the 400 mcg baseline and also includes iron, calcium, and vitamin D. Starting a prenatal vitamin a few months before trying to conceive builds up your nutrient stores so they’re ready when the pregnancy begins drawing on them.
Schedule a Preconception Checkup
A preconception visit is a medical appointment specifically designed to identify and address health issues before pregnancy. Your provider will typically run a panel of blood tests that checks for anemia through a complete blood count, determines your blood type and Rh factor, and screens for infections including hepatitis B, hepatitis C, HIV, chlamydia, and syphilis. You’ll also be tested for rubella immunity, since rubella during pregnancy can cause serious birth defects, and if you’re not immune, you can get vaccinated before conceiving.
This visit is also the time to review any medications you’re currently taking. Some common drugs can cause birth defects and need to be stopped or switched well in advance. Isotretinoin, used for severe acne, is one of the most dangerous: it can cause defects of the skull, heart, and brain even with brief exposure, and you need to wait at least one month after stopping before trying to conceive. Cholesterol-lowering statins should also be discontinued before pregnancy. Blood pressure medications in the ACE inhibitor class typically need to be swapped for a pregnancy-safe alternative. Don’t stop any medication on your own. Bring a full list to your preconception appointment so your provider can make safe substitutions.
If you have a chronic condition like diabetes, thyroid disease, epilepsy, or high blood pressure, getting it well-controlled before conception significantly reduces pregnancy risks.
Plan for Coming Off Birth Control
How quickly fertility returns depends on what type of contraception you’ve been using. A large Boston University study found that IUD users (both hormonal and copper) and implant users had the shortest wait, averaging about two menstrual cycles before normal fertility returned. Pill and vaginal ring users waited an average of three cycles. Patch users averaged four cycles.
Injectable contraceptives like the shot take the longest, with fertility returning in five to eight cycles on average, because the hormone suppresses ovulation for an extended period. If you’re on the shot and planning a pregnancy in the next year, talk to your provider about transitioning to a shorter-acting method or stopping early to give your body time to resume regular cycles.
Know Your Fertile Window
Your fertile window is about six days per cycle: the five days before ovulation and the day of ovulation itself. Sperm can survive in the reproductive tract for up to five days, while an egg only lives for 12 to 24 hours after it’s released. This means you don’t need to time sex to the exact moment of ovulation. Having sex every one to two days during the days leading up to ovulation gives you the best chance.
Tracking ovulation can be as simple as monitoring cervical mucus (it becomes clear and stretchy near ovulation) or using over-the-counter ovulation predictor kits, which detect a hormone surge that happens one to two days before the egg is released. If your cycles are irregular, tracking can help you and your provider figure out whether you’re ovulating consistently.
Adjust Your Diet and Caffeine Intake
A nutrient-rich diet supports hormone balance and egg quality. Focus on whole grains, leafy greens, lean protein, and healthy fats. Fish is an excellent source of omega-3 fatty acids, which support fetal brain development, but mercury levels vary by species. The FDA recommends eating two to three servings per week (four ounces per serving) of low-mercury fish like salmon, shrimp, tilapia, and canned light tuna. You can have one serving per week of moderate-mercury options like albacore tuna or yellowfin tuna, but skip the high-mercury fish entirely. Bigeye tuna, swordfish, shark, king mackerel, and tilefish are all in the “avoid” category.
For caffeine, the recommended limit is 200 mg per day when you’re trying to conceive. That’s roughly two standard cups of coffee. Higher intake has been associated with longer time to conception and increased miscarriage risk in some studies. Tea, energy drinks, and chocolate also contribute to your daily total.
Reach a Healthy Weight
Body weight has a direct effect on ovulation. The healthy BMI range for fertility is 18.5 to 24.9. Being above or below this range can cause hormonal imbalances that disrupt or stop ovulation entirely. Women who are underweight may stop having regular periods because low body fat suppresses the reproductive hormones needed to release an egg each month. Women with a higher BMI may ovulate irregularly or experience changes in hormone levels that reduce the chance of conception each cycle.
You don’t need to hit a perfect number. Even modest weight changes, losing 5 to 10 percent of body weight if you’re above the healthy range or gaining a few pounds if you’re below it, can meaningfully improve ovulation patterns. Crash dieting is counterproductive because it stresses the body and can suppress fertility further. Gradual changes through balanced eating and regular movement are more effective.
What Your Partner Can Do
Sperm quality matters just as much as egg quality, and it responds to lifestyle changes. New sperm take about two to three months to fully develop, so any improvements your partner makes now will show up in sperm quality roughly a quarter-year later. Starting early gives those changes time to take effect.
The key factors for healthy sperm are straightforward. Maintaining a healthy weight is important because a higher BMI is linked to lower sperm count and reduced motility (how well sperm swim). Smoking lowers sperm count, and heavy alcohol use reduces both count and testosterone levels. Stress can interfere with the hormones needed for sperm production.
Heat is a less obvious factor. The testicles need to stay slightly cooler than body temperature to produce sperm effectively. Frequent use of hot tubs, saunas, or laptops placed directly on the lap can raise scrotal temperature enough to impair sperm production. Wearing loose-fitting underwear and avoiding prolonged sitting may help. These aren’t dramatic interventions, but they add up when combined with other healthy habits.
Cut Out Harmful Substances
Alcohol, tobacco, and recreational drugs should all be eliminated before you start trying. There is no known safe level of alcohol during pregnancy, and since many women don’t realize they’re pregnant for several weeks, stopping before conception closes that gap. Smoking reduces fertility in both men and women and increases the risk of miscarriage, preterm birth, and low birth weight. If quitting feels difficult, your preconception visit is a good time to ask about cessation support.
Environmental exposures also deserve attention. Limit contact with pesticides, solvents, and lead when possible. If either partner works with chemicals or in industrial settings, bring that up with your provider so you can take appropriate precautions.
Build Healthy Habits Before Pregnancy Demands Them
Regular physical activity, consistent sleep, and stress management are easier to establish before the fatigue and nausea of early pregnancy arrive. Aim for 150 minutes of moderate exercise per week, which could be brisk walking, swimming, or cycling. Exercise supports hormonal balance, helps with weight management, and improves mood, all of which benefit fertility.
Chronic stress elevates cortisol, which can interfere with the hormonal signals that trigger ovulation. You don’t need a formal meditation practice. Anything that genuinely helps you decompress, whether that’s time outdoors, a creative hobby, or regular social connection, counts. The preconception period is also a good time to establish a relationship with an OB-GYN or midwife you trust, so that transition into prenatal care feels seamless once you get a positive test.
