At 7 weeks pregnant, your baby is about the size of a blueberry, measuring around 0.51 inches (1.3 cm). It’s incredible how much your little one has grown since conception. The development of your baby has reached some significant milestones at this stage, and you might notice some changes in your body too.
Your baby’s brain and face are starting to form, and the tiny arm and leg buds are differentiating into fingers and toes. Your baby’s heart is also beating around 150 times per minute, and the mouth and tongue are developing. By now, your baby’s trunk and head are nearly equal in length, and the embryo has curves that give your little one a C-shape.

Changes in Your Body
As your baby grows inside you, your body is also going through many changes. The pregnancy hormone progesterone causes your uterus to expand, which can lead to morning sickness, fatigue, and breast tenderness. You might also notice that your sense of smell is heightened, and you’re experiencing mood swings.
Some women might start to experience constipation, bloating, or indigestion due to the hormone changes in their body. It’s essential to take extra care of yourself during this period and try to stay hydrated by drinking plenty of water and eating a healthy, well-balanced diet.
What to Expect
At this stage, it’s crucial to take proper care of yourself and your growing baby. You can expect to have regular prenatal check-ups with your healthcare provider to monitor your baby’s development and ensure that you’re both healthy.
It’s also an excellent time to start thinking about your birthing plan and seeking information about the different childbirth options available to you. Consider taking prenatal classes, joining support groups, and learning relaxation techniques to help you cope with labor and delivery.
Frequently Asked Questions

2. Should I exercise during pregnancy?
Exercise is usually safe during pregnancy, but it’s essential to speak to your healthcare provider before starting any new workout routine. Aim for low-impact activities such as walking, swimming, or prenatal yoga, and avoid high-intensity exercises or contact sports.
3. Can I keep working during pregnancy?
Many women continue to work during pregnancy and find it manageable with appropriate workplace accommodations. Speak to your employer about any changes that might be necessary, such as reduced working hours, more frequent breaks, or adjustments to your work environment.
4. How much weight should I gain during pregnancy?
The amount of weight you gain during pregnancy depends on your pre-pregnancy weight and other factors. Typically, women with a healthy weight before pregnancy should aim to gain around 25-35 pounds. Speak to your healthcare provider about a healthy weight gain plan that works for you.
5. When should I start shopping for baby items?
It’s never too early to start shopping for baby items, but it’s best to wait until you have a better idea of your baby’s needs and preferences. Consider waiting until after your 20-week ultrasound to start shopping for larger items such as a crib, stroller, or car seat.
