Pregnancy: reliable information for each stage

Pregnancy brings a lot of questions, and it helps to have clear, reliable information. This guide gives a general overview of what happens across pregnancy and where to find good support. Your own midwife or doctor always knows your situation best, so use this as background rather than personal advice.

Getting antenatal care early

One of the most useful things you can do is make contact with a midwife or doctor early. Early antenatal care means you get the right checks, screening offers, and support from the beginning, and it gives you a point of contact for any questions that come up.

The three trimesters

Pregnancy is usually described in three stages, called trimesters.

First trimester (weeks 1–12)

This is when many of the early changes happen. Some people feel well; others experience tiredness, nausea, or other early symptoms. Early antenatal appointments usually begin during this period.

Second trimester (weeks 13–27)

Many people find the middle months more settled. This stage often includes routine checks and screening offers. It's a good time to ask your midwife about anything you want to understand better.

Third trimester (weeks 28–birth)

The final stage focuses on preparing for birth. Appointments typically become more frequent, and you'll talk through your options and plans for labour and delivery.

Looking after yourself

General wellbeing — rest, eating well, staying active in ways that feel comfortable, and avoiding things known to be harmful in pregnancy — supports both you and your baby. Your midwife can give advice tailored to you, including on any specific questions about diet, activity, or symptoms.

When to seek advice

Always contact your midwife, doctor, or maternity unit if something doesn't feel right or if you have symptoms that worry you. Maternity teams expect questions and would always rather hear from you. This guide is general information and does not replace advice from the people looking after your pregnancy.
