A Complete Guide to Pregnancy Care, Trimester by Trimester

Why Antenatal Care Matters

Antenatal care (also called prenatal care) is the regular medical attention you receive during pregnancy. Its purpose is simple: to keep you and your baby healthy, to catch any concerns early, and to help you feel confident and supported. The World Health Organization recommends a minimum of eight antenatal contacts during pregnancy, because regular visits are linked to safer outcomes for both mother and baby.

Every pregnancy is unique, so think of the timeline below as a general guide rather than a strict rule. Your own care plan will be tailored to your health and needs.

First Trimester (Weeks 1-12): Building the Foundation

The first trimester is a time of rapid change. Booking your first antenatal visit early gives your doctor the chance to confirm your due date, review your medical history, and start essential screening.

What to expect at your first visits

• Confirmation of pregnancy and an estimated due date, often with an early ultrasound
• Blood tests to check for anaemia, blood group, and certain infections
• Blood pressure, weight, and a general health review
• A conversation about your medical history and any medications you take

How to care for yourself

Begin or continue a folic acid supplement, which helps protect your baby's developing spine. Eat balanced meals, stay hydrated, and rest when you can. Nausea and fatigue are common and usually ease as the weeks pass. Avoid alcohol, smoking, and unprescribed medicines.

Second Trimester (Weeks 13-27): Often the Most Comfortable

Many women find this the easiest stage. Early nausea typically settles, energy returns, and you may begin to feel your baby move.

Key checkups

• An anomaly (detailed) ultrasound, usually around 18-22 weeks, to check your baby's growth and development
• Screening for gestational diabetes, commonly between 24 and 28 weeks
• Ongoing checks of your blood pressure and, where relevant, your iron levels

This is also a good time to plan, whether that means thinking about your birth preferences, arranging time off work, or asking questions you have been saving up. No question is too small.

Third Trimester (Weeks 28-40): Preparing for Birth

Visits become more frequent now as your doctor monitors your baby's growth and position and watches for any signs that need attention.

What your doctor checks

• Your baby's growth, movements, and position in the womb
• Your blood pressure, to watch for conditions such as pre-eclampsia
• Discussion of your birth plan and signs of labour

Knowing when to call

Contact your doctor or maternity unit promptly if you notice reduced or absent baby movements, vaginal bleeding, severe headache, sudden swelling of the face or hands, blurred vision, or any fluid leaking. These symptoms do not always mean something is wrong, but they should always be checked.

Healthy Habits Across All Three Trimesters

• Attend every scheduled antenatal appointment, even when you feel well
• Eat a varied diet and take recommended supplements such as folic acid and, if advised, iron
• Stay gently active unless your doctor advises otherwise
• Keep your vaccinations up to date as recommended in pregnancy
• Prioritise rest, sleep, and your emotional wellbeing
