5 things to look forward to this week:
1.     Seeing a positive result on the pregnancy test!
2.     Your body getting ready to house a baby.
3.     Being 4 weeks pregnant even though you’ve just found out.
4.     Pregnancy symptoms such as tender breasts, a sure sign you’re pregnant.
5.     Mood swings – with a totally legitimate reason.
Pregnancy symptoms this week:
Many women don’t realise that they are pregnant at this stage. And, in fact, four weeks is the very earliest you can know if you’re pregnant – the first three weeks of pregnancy are actually your last period, ovulation and conception. Early pregnancy symptoms can be very like those you get during a period.

You may have mood swings, cramping (that feels like period pain) and your breasts might feel tender. These pregnancy symptoms can stay with you for a while. Mood swings are caused by changes in your hormones and research shows they are most severe in the first 12 weeks of pregnancy. Warn your partner that you might be a little moody, and be kind to yourself as your body adjusts to the new flood of hormones. You are certainly not alone in this!

Some women notice some light bleeding or spotting during the 4th week of pregnancy. This is perfectly normal and is known as implantation bleeding. It is caused by the embryo implanting itself on the uterine wall. Many women don’t experience any bleeding, so if you don’t bleed it doesn’t mean you aren’t pregnant.

Your baby’s development this week:
At four weeks, the tiny ball of cells that will become your baby is only the size of a poppy seed. This ball of cells is known as a blastocyst and at four weeks it has finished its journey through the fallopian tube and reached the uterus. Here it will implant on to the wall of your uterus and begin to split into the embryo (your baby) and the placenta. The placenta provides all the nutrients and oxygen your baby needs to grow for the next 36 weeks. For now, the yolk sac is providing the nutrients and red blood cells for the embryo.

This week, the embryo will divide into three layers. The inner layer will form your baby’s lungs, liver and digestive system. The middle layer will become the heart, sex organs, kidneys and muscle. The outer layer will become your baby’s nervous system, brain, skin, hair and eyes.

This week’s To Do list:
