Calculate My Exact Due Date

October 2027 Overview

A baby due in October 2027 means you will likely have conceived around January 2027.

In the UK, a October due date means welcoming your baby in the Autumn. Preparing for a newborn requires slightly different approaches depending on the season, especially regarding clothing and room temperature.

Preparing for a Autumn Baby

As the weather cools down, transitional layers like cardigans and cellular blankets are very useful.
Your baby's first few weeks might feature mild days but chilly evenings, so having easily removable layers is practical.
Start preparing for winter walks by looking into pram footmuffs or weather shields.
Ensure you have a reliable room thermometer to keep their sleeping environment around 16-20°C as the heating starts turning on.

Approximate Timeline & Scans

Note: These windows assume a due date in the middle of October. Your actual scan dates will vary depending on your exact due date and your local NHS trust's availability.

First Trimester

Until approx. April 2027

You will have your booking appointment (usually between 8 and 10 weeks). You will also be offered your first ultrasound scan.

Dating Scan Window: Roughly between March and April 2027

Second Trimester

From approx. April to July 2027

Many women find their energy returns during this trimester. You will be offered the anomaly scan, which is a detailed check of the baby's physical development.

Anomaly Scan Window: Roughly between May and June 2027

Third Trimester

From approx. July 2027 onwards

The final stretch leading up to October 2027. You'll have more frequent midwife appointments, discuss your birth preferences, and start maternity leave.

Practical Preparation

Maternity Leave

You must tell your employer about your pregnancy and the date you want to start your Statutory Maternity Leave at least 15 weeks before the beginning of the week your baby is due. This is usually around the time you receive your MATB1 form (around 20 weeks).

Hospital Bag

It's a good idea to have your hospital bag packed by the time you are 36 weeks pregnant. Since you are due in October, factor this timing into your planning so you are ready a month early.
