How your Baby Develops and your Body Responds


Pregnancy is one of the most important journeys that you will ever go on. 

To help you understand as much as possible about your pregnancy, this section will take you through your pregnancy week by week, to the day of the birth of your baby and it will give you information on the things that you should do during the different stages of pregnancy.


Calculate your Expected Date of Delivery

Most people talk about pregnancy lasting for nine months, but wecalender with date highlighted generally measure pregnancy by weeks, lasting 40 - 42 weeks from conception. Your doctor or midwife will calculate the date you can expect your baby to be born based on the first day of your last menstrual period. They base it on you having a regular cycle of 28 days.

To calculate your expected date of delivery (EDD) add seven days and nine months to the first day of your last menstrual period. For example, if the first day of your last period was on the 2nd of March, your expected date of delivery (EDD) is the 9th of December. Most women will go into spontaneous labour between 37 - 42 weeks of pregnancy. There is no way to accurately predict the exact delivery date; we know that first time mothers are more likely to go past 40 weeks.
