When you are 15 weeks pregnant, most women can no longer wear their regular trousers. Time to buy maternity clothes if you haven’t already! Even strangers can probably see that you are pregnant now.
Your baby is growing rapidly and has actually doubled in weight since last week!
What to Expect at 15 Weeks Pregnant

Baby Development When 15 Weeks Pregnant
How Big is My Baby When 15 Weeks Pregnant?
The fetal age of your baby is now 13 weeks. At 15 weeks pregnant, your baby is now the length of an apple or pear at approximately 4 inches long (10 cm) and weighing 2.5 ounces (71 gram). So grab an apple or pear and hold it in your hand. This maybe makes visualizing your baby a bit easier.
What Does My Baby Look Like During Week 15?
Your baby is looking more “baby-like” day by day. So much developed that the baby’s gender can sometimes be revealed in an ultrasound this week – sometimes even earlier!
If you were to peek inside, the blood vessels are now visible through the transparent skin.
The baby continues to grow lanugo and continues to grow it until around week 26 of your pregnancy.
Even eyebrows and scalp hair is starting to become visible and the hair follicles start to produce pigmentation. That does not necessarily mean that a baby born with dark hair will remain dark or light hair will stay that way.
For many babies, the hair color changes during the first year and can be entirely different from those first few months.
Now the baby’s legs have caught up to the rest of the body and are now longer than the arms. Another thing that makes the baby look more like a newborn.
Fetal Development and Abilities
Although everything has been in place for some time, there are still many changes that go on behind the scenes. Your baby is also practicing various abilities that are needed when born.
Bones continue to harden and the marrow of the skeletal system develops more each day that goes by.
Swallowing amniotic fluid helps prepare the nose and upper respiratory tract as the primitive air sacs in the lungs still develop.
Your baby-to-be can now sense light even though the eyes are still fused shut. If you were to shine a flashlight on your belly, your baby is likely to move or turn away from it.
Thumb sucking may be noticed if you were to have an ultrasound now and if you are lucky, the gender of your new baby may be visible. With our third child, I actually got a UL picture to take home of my son’s gender already when 13 weeks pregnant, but that is quite unusual.
If you have decided NOT to check your baby’s gender – or you have already found out – then it can be time to start creating your baby registry! Wow, already!? Yes, why not? It is fun, and you can let it slowly evolve over time.
Mom’s Body When 15 Weeks Pregnant
Body Changes at 15 Weeks
Your uterus is continuing to enlarge as it begins to move above your hipbones now. You may be able to feel it yourself about 3 or 4 inches (7-10 cm) below your navel if you lie down flat on your back and relax.
Your medical practitioner will continuously measure this “fundal height“, which is the distance from the top of your uterus to your pubic bone, to ensure that your baby is growing at a normal rate.
How is your weight gain developing? 15 weeks pregnant, you may notice that you are about 5 pounds (2.3 kg) heavier now than before, and well on your way to gaining the weight you need to help your baby grow and thrive. Find average weekly weight gain during pregnancy here.
You probably need at least one new pair of trousers now or very soon.
Other changes in your body can occur periodically or well throughout the pregnancy depending on your own body and hormones.
Pregnancy Symptoms in Week 15
In addition to the obvious weight gain and growing belly, there are other pregnancy symptoms that you may notice too.
Stuffed up noses or even nosebleeds can be just some of those irritating side effects of the increased blood flow to your mucous membranes.
Another could be headaches, but be sure to discuss any persistent symptoms with your medical caregiver as they may be a sign of something else that needs to be addressed.
Changes in your own hair and skin are common during pregnancy, especially during the 2nd trimester.
Some women find that their hair grows remarkably faster, and even thicker than ever before, while others find that their hair is limper, thinner, or can be dry or oily depending on your skin. Do not be alarmed.
Your body is just dealing with all the necessary preparations for your new baby and you have the side effects to prove it.
However, many women find the second trimester to be relatively easy compared to the first and last parts of pregnancy. So if you do feel well – enjoy it!

Diary of a Daughter
What’s it really like being 15 weeks pregnant…? Here’s a true diary from a 15 weeks pregnant mom (Me..!)
My first week with maternity trousers. Now I feel very pregnant! 🙂
We went skiing this weekend. I could just barely wear my ski pants, and was a bit worried about skiing, but it went great. I took it easy.
