Even though this week counts as week 1 of pregnancy, you are not actually pregnant yet
This week counts as part of your 40 weeks of pregnancy, but you aren't officially pregnant until week 3 as conception occurs about two weeks after your period.
Your egg has left the ovary
You are now ovulating and your egg will begin to travel through the fallopian tubes.
This week you are ovulating, your egg has left the ovary and is travelling down the fallopian tube where it will meet the sperm and fertilise your egg. Although not technically pregnant just yet - hopefully you soon will be!
Start looking at healthy changes you could make to your diet that will stand to both you and you baby's long term health. Opt for lots of fruit and veg, low fat dairy foods, lean meats, fish and wholegrain breads, cereals and pastas. Drink plenty of water, reduce down your caffeine intake and eliminate alcohol completely.
Your baby's sex is already decided
Your egg has now been fertilised and the first steps in your baby's development have begun. Whether you are having a boy or a girl is now decided.
Your baby is called an embryo at this stage
Until around week 8 of pregnancy the medical term for your baby is an embryo. After this they will be referred to as a foetus.
Your baby will double in size by the end of the week
You may not feel like you are pregnant yet but that doesn't mean that there isn't a lot happening! Even at this early stage your baby is developing rapidly and the neural tube is already forming.
Your baby's heart will soon start to beat
Already, your baby is receiving nutrition and oxygen through your placenta. This will continue to pass them nutrients from you and oxygen throughout the next 8 months.
Baby's lungs, liver and pancreas are all being formed
You may be feeling tired at the moment and it is no wonder with all that's going on inside you. Your body is getting used to lots of physical changes and your baby is growing rapidly.
