PLANNING FOR PREGNANCY: KEY INFORMATION BEFORE YOU START TRYING

A couple sitting together and talking about planning a pregnancy

Deciding to have a baby is exciting, and a little preparation before you start trying can make a real difference for both you and your future baby. You do not need to be perfect. Most of the steps below are simple habits and a conversation with your doctor. This guide covers the key information to know before you start trying for a baby.

1. Book a pre-pregnancy check-up

A visit to your doctor or midwife before you start trying is one of the most useful steps. It is a chance to:

  • Review your medical history, and any long-term conditions such as diabetes, thyroid problems, high blood pressure, or epilepsy
  • Check which of your medicines are safe in pregnancy
  • Check that your cervical screening (smear test) is up to date
  • Ask about tests for infections such as HIV, hepatitis B, syphilis, and chlamydia, which can affect fertility or be passed to a baby
  • Check your immunity to rubella (German measles) and chickenpox, and ask which vaccinations you need

Important: do not stop prescribed medicines on your own. Talk to your doctor first, because stopping some medicines can be harmful, while a few others do need to be changed before pregnancy.

2. Start folic acid before you conceive

Folic acid is a B vitamin that helps prevent neural tube defects, such as spina bifida, in the baby.

  • Most women are advised to take 400 micrograms (mcg) of folic acid every day while trying for a baby and until week 12 of pregnancy.
  • Ideally, start before you try to conceive. Some guidance recommends starting at least 2 to 3 months before.
  • Some women need a higher dose, which is available only on prescription. This applies, for example, to women with diabetes, a previous pregnancy affected by a neural tube defect, a high BMI, or who take certain medicines. Ask your doctor if any of these apply to you.
  • If you did not take folic acid before pregnancy, start as soon as you find out you are pregnant.

Foods such as green leafy vegetables and fortified cereals contain folate, but a supplement is still recommended.

3. Look after your health and lifestyle

  • Eat a balanced diet: vegetables, fruit, whole grains, protein, and dairy or calcium-rich foods.
  • Aim for a healthy weight: being very underweight or overweight can make it harder to conceive. If you want to lose weight, do it gradually, and avoid crash diets.
  • Move regularly: walking, swimming, or any activity you enjoy helps your overall health.
  • Stop smoking: it affects fertility in both women and men, and it is harmful in pregnancy. Ask your doctor or pharmacist for support.
  • Avoid alcohol: the safest approach when you are trying for a baby is not to drink.
  • Limit caffeine: a common recommendation is no more than 200 mg a day, about two cups of coffee.
  • Avoid recreational drugs.
  • Manage stress and sleep: rest matters, and so does your mental health.

4. Do not forget your partner

Fertility depends on both partners. Men can support a healthy conception by stopping smoking, reducing alcohol, keeping a healthy weight, avoiding anabolic steroids, and checking with a doctor if they have any concerns. A healthy lifestyle for both of you also helps you stay motivated together.

5. Understand your cycle and your fertile days

Your fertile window is the few days each month when pregnancy is possible. Ovulation usually happens about 12 to 16 days before your next period starts, and the fertile window includes the days before ovulation and the day of ovulation itself. If your cycles are regular, you can estimate this with an ovulation calculator, and you can also watch for signs such as clear, stretchy cervical mucus.

You do not have to time everything perfectly. For most couples, having sex every 2 to 3 days throughout the cycle gives a good chance of conceiving, and many couples find it less stressful than trying to time ovulation exactly.

You can estimate your fertile days and your due date with the free Ovulation Calculator and Due Date Calculator in the sidebar of this blog. Remember that they are estimates only.

6. How long does it usually take?

Many people become pregnant within a year. According to NHS information, about 84 out of 100 couples who have regular unprotected sex conceive within a year, and about 92 out of 100 within two years. It is normal for it to take several months, even when everything is fine. Fertility declines gradually with age, and more noticeably after the mid-30s.

7. When to ask a doctor for help

  • You have been trying for 12 months without success (and you are under 35)
  • You are about 35 or older and have been trying for 6 months
  • Your periods are irregular, very painful, or absent
  • You have a known condition that may affect fertility, such as endometriosis or polycystic ovary syndrome (PCOS)
  • You have had repeated pregnancy losses
  • You or your partner have a known fertility concern, or have had pelvic infections or surgery

Ask for help earlier if any of the above applies to you. Fertility assessment is usually done as a couple, and early advice can save time.

8. Think about contraception, work, and money

  • Contraception: ask your doctor when to stop, as it depends on the method. Many methods have no long-term effect on fertility, but periods may take a little time to return to normal.
  • Work and rights: check your workplace policies on leave and flexibility.
  • Budget and support: think about costs, childcare, and who can help you after the birth.
  • Emotional readiness: talk openly with your partner about expectations, roles, and fears. It is normal to feel both excited and nervous.

Frequently asked questions

Do I really need to take folic acid before I am pregnant?

Yes, it is recommended. The neural tube forms very early, often before you know you are pregnant, which is why folic acid is advised before conception and during the first 12 weeks.

Do I need to stop birth control long before trying?

It depends on the method. Some can be stopped and you can try right away, while others may need a few weeks or a check-up. Ask your doctor.

Can stress stop me from getting pregnant?

Everyday stress is not usually the main cause of difficulty conceiving, but long-term stress can affect your sleep, cycle, and wellbeing. Looking after your mental health is still important.

When should I take a pregnancy test?

Most home tests work best from the first day of a missed period. If you are unsure, repeat the test a few days later.
