The first week of pregnancy occurs before you actually conceive your new baby. It’s a little confusing – doctors begin counting the weeks of your pregnancy from the date your last menstrual bleeding started, not from the date you conceived. Conception, that very important moment at which your partner’s sperm fertilises your egg, does not occur until approximately two weeks after the start of your last period. However, your body is already preparing itself for pregnancy, should conception occur, so this week officially marks the beginning of the pregnancy.

You’ll be amazed at all the work your body needs to do to produce the hormones which signal your body to prepare for pregnancy in Week 1. Even though you are not yet pregnant, your body is working hard to prepare an egg for fertilisation, and to prepare your womb to nourish the egg should it be fertilised. Find out all about how your body is changing this week.
