Baby's Development

Did you know that this week starts with the first day of your menstrual period? On average, you will ovulate in 2 weeks’ time and that is when the real magic will begin!

 

Your Body

Your menstrual cycle will last about 28 days and during this first week you will shed the lining of your womb and have your period. Your period will last its usual 5-7 days. This is going to be a very special cycle.

Baby's Development

Your body is producing a special hormone called follicle-stimulating hormone (FSH) that will help mature around 1 to 2 dozen follicles inside your ovaries.

 

Your Body

Fertilisation has not yet occurred. The lining of the womb, your uterus will start to thicken once your menstrual flow ends. This is where your egg will settle and start to grow once it has been fertilised.

Baby's Development

This week a mature egg will be released from your ovary and start its journey down your Fallopian tube. You may feel some pain on your right or left side as ovulation occurs.   It takes your egg around 5 days to travel down your tube to the uterus. As soon as your egg is fertilised the cells begin to divide making more and more cells very quickly. During this time the code for every one of your baby’s features will be set – gender, hair colour, height…

 

Your Body

Your body is now producing a bunch of hormones that will make your vaginal mucous more watery so the sperm can hurry through to find that egg hiding high up in your Fallopian tube. Sperm can survive for about 5 days inside your body. Your egg will survive for only 24 hours after ovulation!! This means your ‘fertile window’ opens 4-5 days before ovulation and closes just 24 hours after ovulation. This is when you are most likely to conceive.

The fertilised egg is just a bundle of cells multiplying rapidly at the moment.  This week the fertilised egg will burrow into the lining of your uterus. The high levels of progesterone have made the lining of your uterus thick and spongy. The special cells that have formed are ready to develop into the amniotic sac and your little embryo with its own placenta.

 

Your Body

Your body will start producing another hormone, the human chorionic gonadotrophin (hCG) that will maintain high levels of progesterone to ensure that your new little embryo survives. By the end of this week you are likely to have a positive home pregnancy test. You may start to feel a little bloated and you may experience some light spotting known as ‘implantation bleeding’.

Baby's Development

This week your little embryo’s neural tube that will form the brain and spinal cord is starting to develop. Even the tiny buds that will become arms and legs are starting to form. The heart is growing quickly and will start to beat by next week! The placenta is not fully developed yet and a single yolk sac feeds your little embryo that is nestled inside the fluid filled amniotic sac. Even the umbilical cord can be seen this week.

 

Your Body

You may be feeling tired and not have much energy this week. Your bladder is super sensitive and you are off to the loo more often than usual. You and your partner may celebrate together or you may both have quite different reactions as you come to terms with your pregnancy. Becoming parents is a huge step whether it is for the first time or maybe you will be welcoming another baby into your family.

245

Baby's Development

Your little embryo is now about 4mm long and the face and neck are starting to form. Little spots that will become those beautiful eyes are starting to develop. The brain and spine (the neural tube) is starting to close. This week your baby’s heart will start to beat, first slowly around 60 beats per minute then quickly speed up to 160-170 beats a minute.

 

Your Body

With all these changes happening inside your uterus, your hormones are really super active. Now you will certainly feel different, maybe just some moody patches or possibly feeling nauseous and even vomiting. Some smells, foods or even just brushing your teeth can make your mouth fill with saliva and have you running to the bathroom to throw up. You feel pretty average this week but you are actually amazing – your baby has a heartbeat of its own!!

238

Baby's Development

Well your little embryo is now 8mm tall with little arms and legs growing quickly. The spine is easily identified on the scan with a precise row of tiny immature bones. Inside the head all the sensory systems within the inner ear are developing that will guide both hearing and movement. A sense of touch around the mouth and lips is starting to develop. The liver has started to make blood cells and the lungs, stomach and intestines are all forming this week.

 

Your Body

Your body is now producing so much oestrogen and progesterone to support your pregnancy. Your breasts may feel larger and very sensitive. Getting outdoors for some fresh air and exercise will do you good. Start focusing on a healthy diet and drink plenty of water every day. It’s time to be sure you have booked your first appointment with a midwife or your GP. You will want to have all your booking bloods done and maybe even that early dating scan.
