Preconception Health Checklist: What to Do Before You Try to Conceive
Deciding you want to have a baby is one of the biggest decisions of your life. And while most of the conversation about conception focuses on what happens after a positive pregnancy test, the three to six months before you start trying may be the most important window of all.
Preconception health the state of your physical and mental health before pregnancy has a direct and measurable impact on your ability to conceive, the health of your pregnancy, and the long-term health of your child. Yet most women receive almost no guidance on it unless they specifically seek it out.
This checklist gives you exactly what you need to do before you start trying organized by category, evidence-based, and written so you can actually use it.
Why Preconception Health Matters More Than Most Women Know
By the time a pregnancy is confirmed usually around four to six weeks the embryo's neural tube has already begun forming. The heart is already beating. Critical early development has been underway for weeks, often before a woman even knows she is pregnant.
This means that the nutritional status, hormonal environment, and health conditions present before conception directly shape early fetal development. Starting prenatal vitamins after a positive test is better than not starting them at all but starting them three months before you begin trying is significantly more effective, because it takes time for folate and other key nutrients to reach optimal levels in the body.
Preconception care is not about perfection. It is about giving your body and your future pregnancy the best possible foundation.
The Preconception Health Checklist
Schedule a Preconception Visit With Your Provider
This is the most important first step and the one most women skip. A preconception visit also called a preconception counseling appointment is a dedicated appointment with your OB-GYN, midwife, or primary care provider specifically to discuss your plans to conceive. It is different from a routine annual exam.
At this visit, your provider will review your medical history, current medications, vaccination status, family history, and any conditions that may need to be optimized before pregnancy. They will also order baseline lab work relevant to conception and early pregnancy.
Ask for:
A complete blood count (CBC) — screens for anemia
Thyroid stimulating hormone (TSH) — thyroid dysfunction is common in women and directly impacts both fertility and early pregnancy
Rubella and varicella immunity — if you are not immune, vaccination before pregnancy is essential (these vaccines cannot be given during pregnancy)
Sexually transmitted infection screening — including HIV, syphilis, chlamydia, and gonorrhea
Blood type and Rh factor — important for pregnancy management
Fasting glucose or HbA1c — screens for pre-diabetes or insulin resistance, both of which affect fertility and pregnancy outcomes
Vitamin D level — deficiency is extremely common and linked to reduced fertility and higher miscarriage risk
Carrier screening — genetic testing that identifies whether you or your partner carry genes for conditions like cystic fibrosis, spinal muscular atrophy, or sickle cell disease
Start a Prenatal Vitamin Now, Not After a Positive Test
The single most evidence-backed preconception recommendation is to begin taking a prenatal vitamin containing folate (or folic acid) at least three months before trying to conceive and ideally six months before.
Why folate is non-negotiable: Neural tube defects including spina bifida develop in the first 28 days of pregnancy, before most women know they are pregnant. Adequate folate levels at the time of conception and in those earliest weeks reduce the risk of neural tube defects by up to 70 percent. You cannot build adequate folate levels overnight; it takes weeks of consistent supplementation.
What to look for in a prenatal vitamin:
Folate or methylfolate (not just folic acid, particularly if you have an MTHFR gene variant that affects folate metabolism) at least 400 to 800 mcg
Iron — supports blood volume expansion in early pregnancy
Iodine — essential for fetal thyroid and brain development; frequently missing from prenatal vitamins
Omega-3 DHA — supports fetal brain and eye development; look for at least 200 mg DHA
Vitamin D — aim for at least 600 to 1,000 IU, more if your blood levels are low
Choline — emerging research strongly supports choline's role in fetal brain development; many prenatal vitamins still do not include adequate amounts
Review All Medications and Supplements
Some medications are not safe during pregnancy and need to be changed or stopped before conception not after a positive test. This includes certain acne medications (isotretinoin/Accutane must be stopped months before attempting conception), some blood pressure medications, certain antidepressants, and many supplements.
Bring a complete list of everything you take including over-the-counter medications, herbal supplements, and vitamins to your preconception appointment. Your provider will advise on what to continue, modify, or discontinue.
Get Up to Date on Vaccinations
Certain infections pose serious risks to pregnancy and fetal development and some of the vaccines that protect against them cannot be administered during pregnancy. Vaccination before conception is the window to catch up.
Check your immunity or vaccination status for:
Rubella (German measles) — rubella infection during pregnancy causes severe fetal abnormalities; confirmed immunity is essential before conceiving
Varicella (chickenpox) — infection during pregnancy carries serious risks; if not immune or vaccinated, get vaccinated at least one month before trying to conceive
Hepatitis B — complete the series before pregnancy if not already immune
COVID-19 — current guidance supports being up to date before and during pregnancy
Influenza — annual flu vaccination is recommended during pregnancy; getting vaccinated before conception is reasonable
Optimize Your Weight
Both underweight and overweight BMI can disrupt ovulation and make conception more difficult. Excess body fat produces estrogen, which can disrupt the hormonal balance needed for regular ovulation. Very low body fat can suppress the hypothalamic-pituitary-ovarian axis and cause cycles to become irregular or stop entirely.
This is not about achieving a specific number on a scale. It is about supporting regular ovulation, hormonal balance, and a healthy uterine environment. Even modest weight changes five to ten percent of body weight in either direction can restore ovulatory function in women whose cycles have been disrupted by weight.
Work with your provider on a realistic, sustainable approach rather than crash dieting, which can itself disrupt hormones and nutrition.
Address Chronic Conditions Before Conception
Several common health conditions directly affect fertility and pregnancy outcomes and are best managed and stabilized before conception, not during it.
Conditions to discuss with your provider:
Thyroid disorders — hypothyroidism and hyperthyroidism both affect fertility and carry pregnancy risks; TSH should be optimized before conceiving and monitored closely throughout pregnancy
PCOS (polycystic ovary syndrome) — affects ovulation directly; management before conception improves ovulatory regularity and reduces gestational diabetes risk
Diabetes and pre-diabetes — blood sugar control at conception significantly reduces the risk of birth defects; HbA1c should ideally be in the normal range before trying to conceive
Hypertension — some blood pressure medications are not safe in pregnancy; medication review and blood pressure optimization before conception is important
Depression and anxiety — mental health conditions benefit from stable management before the physical and emotional demands of pregnancy; medication review with a provider familiar with pregnancy safety is essential
Endometriosis and fibroids — depending on severity and location, these may warrant evaluation or treatment before attempting conception
Stop Smoking, Limit Alcohol, Reduce Caffeine
Smoking is one of the most damaging things you can do to egg quality and ovarian reserve. It accelerates the loss of eggs, damages DNA in eggs, reduces IVF success rates, and significantly increases miscarriage risk. Quitting before conception not just after is the evidence-based recommendation. Your partner's smoking also affects sperm quality.
Alcohol — no safe level of alcohol in pregnancy has been established. Current guidance recommends stopping or significantly limiting alcohol when actively trying to conceive. Heavy alcohol use impairs ovulation and reduces fertility in both partners.
Caffeine — evidence supports limiting caffeine to under 200 mg per day (roughly one to two cups of coffee) when trying to conceive and throughout pregnancy. Higher intake is associated with modestly increased miscarriage risk.
Track Your Menstrual Cycle
If you are not already tracking your cycle, start now before you begin trying. Understanding your cycle length, ovulation timing, and any patterns worth noting gives you and your provider valuable information.
What to track:
First day of each period (day 1)
Cycle length (day 1 to the next day 1)
Cervical mucus changes fertile cervical mucus (clear, stretchy, egg-white consistency) signals approaching ovulation
Basal body temperature (BBT) — a slight rise of 0.2 to 0.5°F confirms ovulation has occurred
LH surge via ovulation predictor kits (OPKs) — the most reliable at-home indicator of the fertile window
Three months of cycle data before you start trying gives your provider a useful baseline and helps identify any irregularities worth investigating before conception.
Support Your Mental Health
The preconception period carries its own emotional weight the anticipation, the uncertainty, the complex feelings that come with this decision regardless of your circumstances. Establishing emotional support before you begin trying sets a strong foundation for the months ahead.
Consider:
Discussing your plans, hopes, and concerns with your partner to align expectations
Connecting with a therapist or counselor particularly if you have a history of anxiety, depression, pregnancy loss, or trauma
Building your support network who will you lean on during this process?
Setting realistic timelines most healthy couples under 35 conceive within six to twelve months of trying; most couples over 35 conceive within six to twelve months as well, though the timeline for seeking support is shorter
Mental health is reproductive health. Both deserve attention before pregnancy begins.
Your Partner's Health Matters Too
Male factor infertility accounts for approximately 30 to 40 percent of all fertility challenges and preconception health applies to partners as well. Sperm take approximately 74 days to develop (roughly two and a half months), which means what your partner does now directly affects the sperm available for conception in the next cycle.
Encourage your partner to:
Get a preconception checkup including semen analysis if there are any concerns
Stop smoking, smoking damages sperm DNA
Limit alcohol and recreational drug use
Avoid prolonged heat exposure (hot tubs, laptops directly on the lap, tight underwear) heat reduces sperm production
Take a male fertility supplement containing antioxidants vitamins C and E, zinc, folate, and CoQ10 have evidence supporting sperm quality
Manage chronic conditions including diabetes, hypertension, and thyroid disease
