Spring has a way of making people think about new beginnings. If starting a family is on your mind this year, you’re probably focused on ovulation tracking apps and prenatal vitamins. Those things matter — but the most important step most women overlook is a preconception visit before they start trying.
The three months before conception are one of the most influential windows in a future pregnancy. What you do — and don’t do — during this time affects egg quality, early fetal development, and your body’s readiness for the demands ahead. Here’s what actually matters.
Start With a Preconception Visit
A preconception checkup is different from a routine annual exam. Your provider will review your health history, assess any chronic conditions, evaluate medications that may need to be switched to pregnancy-safe alternatives, and make sure your vaccinations are current. Some vaccines require a waiting period before you can safely try to conceive, so timing matters.
Blood work at this visit typically checks for anemia, thyroid function, immunity to rubella and chickenpox, and blood sugar. If you or your partner have a family history of genetic conditions, this is also the time to discuss carrier screening.
Don’t wait until you’re already trying to schedule this visit. Many of the adjustments that make the biggest difference — starting folic acid, switching medications, treating an undiagnosed thyroid issue — need several weeks to take effect.
Folic Acid: Start Now, Not After a Positive Test
Neural tube defects occur in the first 28 days of pregnancy, often before a woman knows she’s pregnant. The American College of Obstetricians and Gynecologists recommends beginning folic acid supplementation — at least 400 to 800 mcg daily — at least one month before trying to conceive, and ideally three months ahead.
A prenatal vitamin with adequate folic acid is the simplest way to cover this. Start taking one now, regardless of how soon you plan to begin trying.
What to Eat, What to Limit
Fertility nutrition isn’t about a strict diet — it’s about consistency. Focus on leafy greens, colorful vegetables, lean proteins, healthy fats, and whole grains. Limit caffeine to under 200mg daily (roughly one 12-ounce coffee). Cut back on alcohol; no amount is proven safe during the conception window or early pregnancy.
High-mercury fish — shark, swordfish, king mackerel, and tilefish — should be avoided both during pregnancy and when trying to conceive. Salmon, sardines, and shrimp are low-mercury options with beneficial omega-3s that support hormone production.
Address Lifestyle Factors That Affect Fertility
Moderate exercise improves fertility outcomes. Aim for 30 minutes of moderate activity most days — walking, swimming, cycling, yoga. Very high-intensity training can disrupt ovulation in some women, so balance is important if you train heavily.
If you smoke, quitting is the single most impactful change you can make before trying to conceive. Smoking damages eggs, reduces fertility, and significantly increases miscarriage risk. Your provider can connect you with cessation resources.
Chronic stress disrupts hormonal signaling and can affect cycle regularity. Spring is a natural moment to evaluate what’s draining your energy and build in more restoration — not as a luxury, but as part of your preconception plan.
Understanding Your Cycle
Start tracking your menstrual cycle now if you aren’t already. Note cycle length, any spotting, and changes in cervical mucus. This data helps you identify your fertile window, flags potential irregularities worth discussing with your provider, and gives baseline information that’s useful if conception takes longer than expected.
If your cycles are irregular or you’ve had prior pregnancy losses, mention this at your preconception visit rather than waiting to see what happens.
The Bottom Line
Preconception planning isn’t about perfection — it’s about giving yourself the best possible foundation before you begin. A single visit, a prenatal vitamin, and a few consistent habits can make a meaningful difference.
Spring is a good time to begin. Schedule a preconception consultation to review your health, address any concerns, and create a personalized roadmap for your path to pregnancy.
