Your Baby's Development at 7 Weeks

Size and Growth

At 7 weeks, the embryo is as big as a blueberry, measuring approximately 10mm from the top of the head to the bottom. This measurement is called the crown-rump length. Although tiny, this week is pivotal for your baby's growth.

Development of the Organs, Systems and Limbs

The baby's brain and face are rapidly developing. Tiny nostrils become visible, and the eye lenses start forming. The brain grows and develops very quickly at this stage, making the head look very over-sized in comparison to the body. Your baby's eyes and ears are also continuing to form. Although the outer ears are not yet visible, the inner ears are starting to develop. Your baby's gender will have been determined at conception so your tiny boy or girl is growing rapidly, before you even know their gender they've developed a beating heart and a tiny face!

Cartilage is forming on the limb buds, which will eventually become the bones of the legs and arms. The ends of the arm buds flatten out to resemble paddles; these will eventually form into your baby's hands at around week 8.

Nerve cells are multiplying and developing, and along with the developing brain, will become the nervous system.

Heartbeat

One of the most exciting developments this week is the baby's heartbeat. With a heart rate about twice as fast as yours, it's sometimes possible to see it on an ultrasound.

Your Body at Week 7

Physical Changes

At 7 weeks pregnant, your uterus is now the size of a lemon. You might notice physical changes in your body. Although it's early for a pronounced baby bump, you might feel bloating. You might also feel tired and nauseous, and your breasts may feel tender. 

Hormonal Changes

The increase in pregnancy hormones like hCG and progesterone significantly impacts your body. These hormones are crucial for sustaining the pregnancy but can also cause noticeable symptoms—some of which may be welcome and some of which may not be. It's so important that in these early weeks, you rest, eat, and drink as you need to. Listen to your body and give it what it needs as it powers through these early weeks of rapid development.


Pregnancy Symptoms at Week 7

The first trimester can be a rough old ride for some women. Rest assured that for most, things start to improve by the 2nd trimester. Our top tip throughout pregnancy is to listen to your body and give it what it needs as it navigates these early weeks. Here are some of the pregnancy symptoms you may experience at week 7:

Nausea and Morning Sickness

Morning sickness is a common symptom around this week. Despite its name, nausea can occur at any time of the day and is one of the more unpleasant pregnancy symptoms to have to deal with. It's thought that 'morning sickness' is a term coined by men who would be out of the house and at work without seeing much of the sickness throughout the day - hence calling it 'morning' sickness.

Fatigue

Increased levels of progesterone can make you feel unusually tired. Your body is also working hard to support the growing embryo, contributing to this fatigue. Go easy on yourself and rest as much as you need.

Breast Changes

Your breasts might feel tender and swollen due to hormonal changes, which prepare your body for breastfeeding. You may want to invest in a soft bra without a wire, and you may notice that your breasts have gone up in size. It's worth investing in your comfort, especially if your breasts feel tender!

Food Aversions and Cravings

Many women experience a change in their sense of taste and smell, leading to specific food aversions or cravings. Listen to what your body is telling you, and avoid any foods that don't sit right—you don't have to eat anything you don't want to. Your comfort is key!

Frequent Urination

The growing uterus starts to put pressure on your bladder, leading to more frequent trips to the bathroom. This can be frustrating, especially as hardly anything comes out when you go to the toilet!

Emotional Changes

Fluctuating hormones can also impact your emotions, leading to mood swings. You might find yourself swinging from happiness to upset in a matter of moments. This is all normal but do be kind to yourself and don't beat yourself up about feeling unstable. Pregnancy is a huge emotional and physical toll for many women!

Managing Symptoms at Week 7

Diet and Hydration

Eating small, frequent meals can help manage nausea. Staying hydrated is also essential. Try eating ginger biscuits - many women find this helps to keep nausea at bay.

Rest

Ensure you get plenty of rest. Listen to your body and rest when you feel tired. If you need to, discuss how you're feeling with your line manager and request to work from home - if this is possible with your line of work.

Emotional Support

Seek support from loved ones or a professional if you're struggling emotionally. Remember that what you're going through is a lot to deal with. If this is your first pregnancy then you'll be experiencing everything for the first time as well as dealing with the change of life that's on the horizon. If this isn't your first baby then you could be managing early pregnancy with a toddler in tow which can be physically draining. Go easy on yourself and talk about how you're feeling with friends and family.

 

Week 7 is a week of significant developments and changes. While it can be challenging, understanding what to expect and how to manage symptoms can help you navigate this week with more ease. Remember, every pregnancy is unique, so it's essential to consult with your healthcare provider for personalised advice.
