The 90 Day Preconception Checklist
The three months before you start trying to conceive might be the most important preparation period you never knew you needed. Those 90 days represent the full maturation cycle of the eggs that will be available for fertilization, the time frame in which meaningful lifestyle changes can take effect, and your opportunity to address any health issues before they become complications. This comprehensive checklist walks you through everything to tackle in those crucial three months, organized by timeline so you can stay on track without feeling overwhelmed.
Month One: Medical Foundation (Days 1-30)
The first month is about establishing your baseline. Schedule a preconception appointment with your OB-GYN or primary care provider and let them know you plan to start trying to conceive. This visit should include a thorough review of your medical history, current medications, and any conditions that could affect pregnancy.
Key medical tasks for month one:
- Blood work: Request a complete blood count, thyroid panel (TSH, free T4), vitamin D level, and rubella immunity status
- Cervical screening: Ensure your pap smear is current
- STI screening: Recommended even if you are using donor sperm, as some infections can affect fertility
- Dental checkup: Gum disease has been linked to pregnancy complications, and dental work during pregnancy has limitations
- Medication review: Discuss any current medications with your provider to ensure they are pregnancy-safe
- Vaccination update: Confirm you are up to date on recommended vaccines, particularly MMR and flu
Start a prenatal vitamin if you have not already. Look for one containing at least 400-800 mcg of folate (methylfolate is preferred over folic acid for some women), along with iron, calcium, vitamin D, and omega-3 fatty acids. A comprehensive fertility supplement like the Couples Pack can provide targeted preconception support beyond a basic prenatal. The American College of Obstetricians and Gynecologists recommends starting folate supplementation at least one month before conception to reduce neural tube defect risk.
Month Two: Lifestyle Optimization (Days 31-60)
With your medical foundation in place, month two focuses on fine-tuning your daily habits to create the best possible environment for conception and early pregnancy.
Nutrition is your most powerful tool during this phase. Research consistently shows that a Mediterranean-style diet, rich in fruits, vegetables, whole grains, legumes, healthy fats, and lean proteins, is associated with improved fertility outcomes. Reduce or eliminate processed foods, trans fats, and excessive sugar. Limit caffeine to 200 mg per day (about one 12-ounce cup of coffee) and consider eliminating alcohol entirely.
Exercise should be moderate and consistent. Aim for 150 minutes of moderate activity per week, such as brisk walking, swimming, yoga, or cycling. Extreme exercise can actually impair fertility by disrupting hormonal balance, so this is not the time to train for a marathon. If you are currently sedentary, start gradually.
Environmental factors to address:
- Switch to natural cleaning products to reduce chemical exposure
- Replace plastic food containers with glass or stainless steel
- Choose personal care products free of parabens, phthalates, and synthetic fragrances
- If you smoke, now is the time to quit (smoking significantly reduces fertility and increases miscarriage risk)
- Evaluate your stress levels and begin a regular stress management practice such as meditation, journaling, or therapy

Month Three: Cycle Tracking and Final Preparations (Days 61-90)
The final month before trying to conceive is when you shift from preparation to practice. If you have not been tracking your menstrual cycle already, this is the month to start in earnest. Use ovulation predictor kits, monitor cervical mucus changes, and consider tracking basal body temperature to identify your personal ovulation pattern.
This is also the month to finalize your conception plan:
- If using donor sperm, select your donor and place your order with enough lead time for delivery
- If using an at-home insemination kit, purchase it and do a practice run with water
- Set up your insemination space with all necessary supplies
- Confirm your support system knows your timeline and is prepared to be available
- If working with a fertility clinic, complete any required intake paperwork and baseline testing
Emotionally, give yourself permission to feel excited and nervous simultaneously. This is a significant step, and the feelings that accompany it are all valid. Consider joining an online community of women on similar journeys for support during the trying-to-conceive period. Our article on cervical mucus as a fertility sign provides detailed guidance on this important tracking method.
For Your Partner (If Applicable)
If you have a male partner contributing sperm, their preconception preparation matters too. Sperm takes approximately 74 days to develop fully, so lifestyle changes made now will affect sperm quality roughly two to three months later.
Key steps for the male partner include limiting alcohol consumption, avoiding hot tubs and saunas (heat can damage sperm), maintaining a healthy weight, taking a male fertility supplement that includes zinc, CoQ10, and folate, and avoiding tight-fitting underwear. Our guide on fertility myths debunked addresses common misconceptions about male fertility as well.
According to the Mayo Clinic, male factor contributes to approximately 30 to 40 percent of fertility challenges, making partner preparation a meaningful part of the overall plan.
