Thinking about getting pregnant?

Some of the most important brain development happens before most people know they're pregnant. The months before conception are a chance to get your body, your mind, and your relationship ready.

Why the months before matter

Day 28

The neural tube, which becomes the brain and spinal cord, forms and closes within about the first month after conception, often before a pregnancy test turns positive.

400 mcg

The CDC recommends that everyone who could become pregnant take 400 micrograms of folic acid every day, starting at least one month before pregnancy, to help prevent neural tube defects.

Both partners

Health habits of the person contributing sperm matter too. Smoking, heavy drinking, and some medications can affect sperm quality.

Could I be pregnant?

Common early signs

  • A missed period
  • Unusual tiredness
  • Tender or swollen breasts
  • Nausea, with or without vomiting
  • Needing to urinate more often

Feelings count too

Mood swings, tearfulness, or a rush of worry can arrive early. If you have a history of depression or anxiety, let your provider know as soon as you find out.

Next steps

Take a home pregnancy test, which is most accurate from the first day of a missed period, then book a prenatal visit to confirm and start care.

Health checks before you try

Vaccines

Make sure you're protected against measles, mumps, and rubella (MMR). Rubella in pregnancy can affect a baby's development, and the MMR vaccine can't be given during pregnancy, so the CDC advises waiting 4 weeks after the shot before trying.

Screenings

Get up to date on cervical screening, and consider testing for sexually transmitted infections for both partners. Many have no symptoms and are treatable.

Vitamins

Take folic acid daily, and ask your provider about vitamin D. In the UK, the NHS recommends a vitamin D supplement for everyone who is pregnant or trying.

Talk to your provider before trying if you or your partner…

  • Live with a condition such as epilepsy, diabetes, sickle cell disease, HIV, or a past cancer treatment
  • Take any prescription or over-the-counter medicine or herbal remedy. Don't stop prescribed medicine on your own; ask about the safest option first
  • Have a known fertility issue, such as endometriosis or low sperm count
  • Find sex difficult or impossible, for example because of a disability
  • Want help to stop smoking, drinking, or using drugs
  • Have been trying for a year, or six months if you're 35 or older

How pregnancy begins

Conception is a journey of several days. Tap each step.

The fertile window

Sperm can survive in the body for up to five days, but an egg can be fertilized for only about 12 to 24 hours after ovulation. That's why the days just before and on ovulation day matter most.

It often takes time

Even when timing is right, conception happens only about 1 in 4 times each cycle at best. Most people under 35 who have sex every 2 to 3 days get pregnant within a year, and chances fall gradually after that; with insemination (IUI), about 3 to 6 rounds is a common window before a doctor reassesses. When to ask for help

Many paths, same biology

Some families conceive with medical help: sperm placed in the uterus (IUI), or eggs fertilized in a lab and transferred as an embryo (IVF). Donor eggs, donor sperm, and surrogacy all build families too, including for LGBTQ+ couples, and trans and non-binary people can carry pregnancies as well.

Both partners' health counts

Sperm take about two to three months to develop, so a partner's alcohol, smoking, and health in the months before conception matter too.

Through our lens: conception is biological, but trying to conceive is also psychological (hope, waiting, and disappointment each month) and social (pressure from family, timing with work, and money). Be gentle with yourselves through the waiting.

Caring for your mental health first

A history of depression, anxiety, bipolar disorder, or trauma doesn't mean you shouldn't have a baby. It means you deserve a plan. People who have had depression before are at higher risk of depression during pregnancy or after birth, and planning ahead is one of the most effective ways to lower that risk.

Talk to your prescriber before you try

If you take medication for mental health, don't stop it on your own. Some medications are considered safe in pregnancy and stopping suddenly can cause relapse. A prescriber can weigh the options with you.

Learn your early warning signs

Write down what your own stress or low mood looks like: sleep changes, pulling away, irritability. Share it with someone you trust so they can notice too.

Build your nervous system skills now

Slow breathing, regular movement, time outdoors, and steady sleep are easier to practice before a baby arrives. They become your toolkit later.

Trying for a while, or grieving a loss? When the path is hard covers infertility, pregnancy loss, and the conditions that affect both body and mood.

Seven steps to plan for pregnancy

From the CDC. Getting ready can look different for different people, so take what fits.

1

Talk to your provider

Bring a list: health conditions, every medicine and supplement you take, vaccines you may need, and daily habits.

2

Take 400 mcg of folic acid daily

Start at least one month before pregnancy, ideally around three months, to help prevent defects of the brain and spine. A prenatal vitamin covers this.

3

Stop alcohol, smoking, and certain drugs

They're linked to premature birth and birth defects, and stopping protects your baby from the start. If stopping feels impossible, that's a reason to ask for help, not a failure.

4

Avoid toxic substances

Some chemicals, metals, fertilizers, bug spray, and cat or rodent feces at home or work can harm reproductive health, for all partners.

5

Care for your body's health

Both higher and lower body weight can affect pregnancy. Your provider can talk with you about what's healthy for your body, without judgment.

6

Learn your family history

It can point to risks for you or your baby. Your provider may suggest genetic counseling, especially after several miscarriages or trouble getting pregnant.

7

Care for your mental health

Everyone feels worried or sad sometimes. If those feelings don't go away or get in the way of daily life, get help. Support is also available if you're in a stressful or abusive situation.

You don't have to wait until it's bad

These free US lines are for parents, partners, and anyone supporting them, during pregnancy and after.

Outside the US, contact your local emergency number or health service. If someone has confusion, hallucinations, or thoughts of harming themselves or the baby, call 911 or go to an emergency room.

Physical warning signs like chest pain, trouble breathing, a severe headache, or heavy bleeding during pregnancy or in the year after birth also need care right away. See urgent warning signs
