Trying to Conceive? What to Do in the 3 Months Before Pregnancy
Why the three months before pregnancy matter so much
In our clinic we often say that pregnancy preparation really begins about 100 days — roughly three months , before you start trying. This isn't just a Traditional Chinese Medicine (TCM) idea. It reflects real biology: it takes around 90 days for a batch of eggs to mature before ovulation, and a similar window for sperm to fully develop. What you do in these three months helps shape the quality of the egg and sperm that may become your baby.
In TCM, this is the time to nourish Jing (essence), build healthy Qi and Blood, and bring the body into balance so it is ready to conceive and carry a pregnancy. In modern medicine, this same window is called "preconception care," and research shows it is one of the most powerful opportunities to improve the chances of a healthy pregnancy.
Here is a simple, practical plan for both partners.
1. Start folic acid now , this is non-negotiable
If you do only one thing from this list, make it this. Taking folic acid before pregnancy significantly lowers the risk of serious birth defects of the baby's brain and spine (neural tube defects).
Most people planning pregnancy should take at least 400 micrograms (0.4 mg) of folic acid every day, ideally in a daily prenatal multivitamin.
Start at least one month , ideally three months , before trying to conceive, and continue through the first trimester.
Some people need a much higher dose (for example, 4 mg daily) , including those with a previous pregnancy affected by a neural tube defect, those with a seizure disorder, or certain other conditions. Ask your doctor whether a higher dose is right for you.
This works because the baby's spine forms very early, often before you even know you are pregnant. Having folate already in your system is what protects those first delicate weeks.
2. Nourish the body with food (for both partners)
In TCM, food is medicine , warm, cooked, nourishing meals support the Spleen and Stomach, build Blood, and strengthen the body's foundation for pregnancy. Modern nutrition research points in a very similar direction. Diets rich in whole foods are consistently linked with better fertility.
Aim for:
Plenty of vegetables and fruits, whole grains, beans and legumes
Fish and omega-3 rich foods (while avoiding high-mercury fish — see below)
Healthy fats such as olive oil, nuts and seeds
Good protein, including more plant protein
A Mediterranean-style pattern of eating, which has the most consistent evidence for supporting conception
Try to reduce:
Trans fats and heavily fried foods
Sugary drinks and fast food
Large amounts of red and processed meat
Fish to limit or avoid: skip high-mercury fish such as shark, swordfish, king mackerel and tilefish, and limit tuna. Mercury can harm fetal development.
3. Reach a healthy, balanced weight
Being either significantly underweight or overweight can make conception harder and raise pregnancy risks. For those carrying extra weight, even a modest loss before pregnancy can improve fertility and lower the risk of complications such as gestational diabetes and high blood pressure. The goal is not a crash diet but gentle, sustainable balance — exactly the kind of harmony TCM aims to restore.
4. Move your body , gently and regularly
Aim for about 30 minutes of moderate activity most days of the week (around 150 minutes a week). Think brisk walking, swimming, cycling, qi gong, tai chi, or yoga. Movement supports healthy circulation of Qi and Blood, helps regulate the cycle, eases stress, and supports a healthy weight.
5. Stop smoking, alcohol, cannabis and recreational drugs
This matters for both partners. Smoking is strongly linked to miscarriage, stillbirth and other serious problems, and it harms egg and sperm quality. Alcohol, cannabis and recreational drugs are also best stopped before trying to conceive. If quitting feels hard, you don't have to do it alone , ask your healthcare provider for support. Keep caffeine moderate (under about 200 mg a day, roughly one to two cups of coffee).
6. See your doctor for a pre-pregnancy check-up
Book a preconception visit to:
Review and optimize any chronic conditions , such as diabetes, thyroid problems, or high blood pressure. For example, getting blood sugar well controlled before pregnancy greatly lowers the risk of birth defects.
Check your medications are safe for pregnancy.
7. Don't forget the father-to-be
Healthy sperm takes about three months to develop, so the father's habits in this window genuinely matter. Research in men preparing for pregnancy links better semen quality with not smoking, limiting alcohol, good sleep, and a healthy diet. Encouraging both partners to prepare together makes the whole process stronger and more of a shared journey.
Where TCM and acupuncture fit in
Alongside all of the above, many couples choose acupuncture and Chinese herbal medicine during these three months to support the body's natural balance. In TCM terms, treatment is individualized ("syndrome differentiation") to nourish essence, regulate the menstrual cycle, warm the uterus, calm the mind, and support healthy ovulation and a receptive endometrium.
What does the research say? Several reviews suggest acupuncture and Chinese herbal formulas may help with certain causes of difficulty conceiving for example, improving ovulation and regularity in conditions such as PCOS and acupuncture is generally very safe. However, the studies so far are mostly small or of limited quality, so these findings are promising rather than definitive. We are honest about this with our patients: TCM is best used as a supportive, complementary part of your preparation not as a replacement for folic acid, a healthy lifestyle, or medical care.
A typical approach is to begin acupuncture and, where appropriate, herbs about three menstrual cycles before trying to conceive, which fits beautifully with the 100-day preparation window.
Your simple 3-month checklist
Start a daily prenatal vitamin with at least 400 mcg folic acid (confirm the right dose with your doctor)
Eat a whole-food, Mediterranean-style diet; limit high-mercury fish, fried food and sugar
Reach a balanced, healthy weight
Move most days of the week
Stop smoking, alcohol, cannabis and recreational drugs; keep caffeine moderate
Book a preconception check-up and review any medications and conditions
Prepare together - dad's health matters too
Consider acupuncture and TCM support to help bring body and mind into balance
A note of encouragement
Preparing for pregnancy is not about being perfect - it is about giving yourself and your future baby the best possible start. Small, steady changes over three months add up to a real difference. Whether you are just starting to think about a baby or have been trying for a while, this is a hopeful, empowering time. We're here to support you every step of the way.
