7 Weeks pregnant

How big is my baby at 7 weeks?

Your baby is continuing to grow at a remarkable pace, its embryonic form is slowly starting to transform into an actual little person, with emerging arm and leg buds, and a beating heart – how amazing? They also have a tiny tail – but that will soon disappear!

Amazingly your baby has already gone through three sets of kidneys by week 7, but this week they’ll start developing their final set which will be ready for waste management. In the coming weeks your baby will start to produce urine which will form part of the amniotic fluid.

Size-wise, your baby is now about 1cm in size and not much bigger than a little bean, bobbing around in your womb.

Facts to know about your baby in week 7

  • Your baby is officially called a 'foetus' which means 'offspring', getting nutrition from the yolk sac rather than the placenta for now.
  • Your baby's heart is beating around 160 beats per minute compared to your 60-100bpm.
  • Your baby starts moving around now.
  • Your baby's hands and feet have webbed fingers and toes.
  • Thumb sucking has been detected in babies from as early as 7 weeks.
  • Your baby's skin is paper thin, almost transparent.

You at 7 weeks pregnant

Seven weeks in, you might be coming to terms with, (or still awaiting!) the nausea on waking, or the other earlier signs of pregnancy. It can be a lot to take in, especially if you have chosen not to let others in on your secret until after your 12 week scan.

Try to avoid being around people who are unwell in these early weeks – some illnesses such as rubella and parvovirus (also known as slapped cheek disease) are mainly picked up by coming into contact with children – so take care! You should also be very cautious around certain animals at this point in your pregnancy, too – ewes and lambs in particular can carry an infection which causes miscarriage, and cat litter trays (cat poo, basically) can cause toxoplasmosis, a parasitic infection.

Your rubella (German measles) immunity will be checked at your booking in appointment, but do let your GP or midwife know as soon as possible if you have come into contact with anyone with German measles or any other illnesses.

What to think about in week 7

When will your little one be arriving? You can get a better idea of your due date before your dating scan by using our pregnancy due date calculator on Bounty.com. This is a good way to begin ensuring you have everything in place for your baby's exciting arrival! 

You'll be having your first appointment with your GP or midwife very soon, if you haven't already done so. Think about any questions you might want to ask them, or things you might need to make them aware of - remember, nothing will seem like a 'silly' or irrelevant query to them (and whatever it might be, it almost certainly will not be the first time they have been asked it!)

At your first midwife appointment, you might be asked for some family health history information - do you need to speak to your parents or get any information together for this? What about your partner's health and family history?

Signs and symptoms at 7 weeks pregnant

Heartburn

It might be very common and harmless in pregnancy but it can cause a significant amount of discomfort. An uncomfortable burning sensation in the upper abdomen, it’s usually triggered by eating - especially spicy and fatty foods. The vast majority of mums-to-be experience heartburn on and off during their pregnancy, not usually continuously. The increase in hormones in your system, namely the hormone Progesterone, which helps to relax and smooth out the muscles of your womb during your pregnancy is often the cause. Heartburn in pregnancy is very common and although it can be uncomfortable and painful it poses no harm to you or your baby. However if it becomes severe your doctor may prescribe medication for you.

Bleeding gums

Your gums may soon begin to bleed when you brush your teeth early in pregnancy even if you’ve never experienced it before. You may also notice your gums bleed when you floss. Expectant mums are especially vulnerable to gum disease (gingivitis) because the increase in blood volume combined with pregnancy hormones means gums can swell and bleed more easily. Do keep flossing to prevent gingivitis and remember, you're entitled to free dental care in pregnancy and for a year after your baby is born, so take full advantage of this.
