At 12 weeks, you’re nearing the end of the first trimester, a significant milestone for both you and your baby.
By now, many of the baby’s vital systems are developing rapidly, and some pregnancy symptoms may begin to ease, offering you a bit more comfort.
This is a week where both subtle and major changes occur in your body and your baby’s development.
Let’s look at what’s happening with your little one and the changes you may experience in yourself, along with some practical safety tips as you navigate these new experiences.
Your Baby at 12 Weeks of Pregnancy
Now that you are 12 weeks pregnant, your baby is developing more recognisable features and continues to grow in complexity.
Your baby is now between 5 to 6 centimetres in length and weighing around 14 grams. They’re now about the size of a small plum.
The baby’s physical development and responsiveness become more pronounced, making each week feel increasingly remarkable.
- Facial features: Previously positioned on the sides of the head, the baby’s eyes are now moving towards the centre of the face, giving a more defined appearance. Eyelids have formed to protect the delicate eye nerves and will remain closed until roughly the seventh month. The ears are also shifting into their proper place, giving the baby a noticeable profile with a defined chin and nose.
- Sensory development: As the brain develops, your baby becomes more responsive to touch. In fact, if you gently prod your tummy, your little one may move or squirm in response, though it’s too early for you to feel these movements.
- Body growth: Your baby’s body is beginning to catch up with the head in terms of growth. While still small, the baby’s body proportions are becoming more balanced, which will continue over the coming weeks.
This is an exciting period as your baby starts to look more like a tiny person with each passing day, and their movements are becoming more purposeful and responsive.
Your Body at 12 Weeks of Pregnancy
At 12 weeks pregnant, you may experience both familiar and unfamiliar symptoms.
Many women may find that certain pregnancy symptoms begin to ease, while new symptoms may appear as the body adapts further.
Here’s what your body is doing at 12 weeks pregnant:
- Hormones: The corpus luteum, a cyst on the ovary that produces progesterone in early pregnancy, is now winding down as the baby’s placenta fully takes over hormone production. This shift often helps reduce symptoms like morning sickness, which may ease for many women around this time.
- Weight gain: As your uterus continues to grow, it may now be felt just above your pubic bone. Weight gain may also start becoming noticeable in areas like the hips, legs, and tummy as your body stores fat reserves to support your baby and prepare for breastfeeding.
- Pregnancy brain: Some women experience ‘pregnancy brain’, or mild forgetfulness, likely due to hormonal changes.
- Mask of pregnancy: You may notice skin pigmentation changes, such as chloasma, which are irregular brown patches on the face and neck, often called the ‘mask of pregnancy’. These usually lighten or fade after delivery.
- Insomnia: A combination of hormonal fluctuations and body changes can cause some sleep disturbances. This may continue until the end of your pregnancy.
- Increased urination: As your uterus grows and presses down on your bladder, you may have to pee every other hour. Increased urination may also disturb your sleep. Try to cut down on evening fluids.
These changes reflect your body’s commitment to supporting a healthy pregnancy, though some symptoms can be challenging.
Staying comfortable and well-rested can go a long way in managing them.
Slow Down, Mummies
All right mums, let’s talk about safety. As you approach your 2nd trimester, you may be more accident-prone.
This may be a combination of ‘pregnancy brain’ and other physical changes that may cause some disorientation.
Pregnancy requires special attention to safety, not only to protect your baby but to prevent injury as your body adapts to new physical demands.
Here are some ways to stay safe and avoid accidents:
- Stay mindful: Slow down, take your time, and be cautious. Whether you’re walking, driving, or going up stairs, a moment’s inattention can lead to unnecessary accidents.
- Dress for comfort and safety: Opt for clothing and shoes that are easy to move in. Loose or long skirts can pose a tripping hazard, so it’s best to avoid them. Swapping high heels for comfortable, sturdy shoes will also help maintain balance as your centre of gravity shifts.
- Use handrails: If you’re climbing stairs, using public transport, or navigating anywhere with steps, hold on to handrails for stability. Small adjustments like these can make a big difference in preventing slips and falls.
- Seatbelt safety: Always wear your seat belt when in a vehicle, positioning the lap belt under your belly and across your pelvis for maximum safety.
Taking these precautions can help you stay safe as your pregnancy progresses, allowing you to focus on your health and wellbeing.
Say ‘Hello’ to Your Second Trimester!
As you reach the 12-week mark, your pregnancy has likely started to feel more real, and your baby’s development has become noticeably complex.
With key features forming and the beginnings of movement and responsiveness, your baby is well on its way to entering the second trimester, which brings its own milestones.
For you, this is a time to embrace the changes in your body, practise good self-care, and take extra safety precautions.
Embracing these changes can make the experience all the more rewarding as you move forward on this journey towards motherhood.
