You're finally hitting the double digits. Ten weeks. For a lot of people, this is the week where the "holy crap, there is a person in there" feeling really starts to sink in because you’re likely looking at an ultrasound or searching for 10 weeks pregnant pictures of fetus to see what on earth is happening inside your uterus. It’s a weird phase. You might still feel like garbage from morning sickness, or maybe you’re just starting to see a tiny bump that looks more like a big lunch than a baby.
But inside? Things are moving fast.
Basically, your baby has officially graduated from being an "embryo" to being a "fetus." That’s a big deal in the medical world. It means the basic groundwork for every single organ system is already laid down. Now, it’s all about fine-tuning.
Looking at 10 weeks pregnant pictures of fetus: The reality vs. the diagrams
When you Google 10 weeks pregnant pictures of fetus, you’re going to see two very different things. First, you'll see those hyper-detailed medical illustrations—the ones where the baby looks like a tiny, translucent person floating in space. Then, you'll see the actual ultrasounds.
The ultrasounds are usually a bit more... "blurry bean."
At ten weeks, the fetus is roughly the size of a kumquat or a large strawberry. We’re talking about 1.2 to 1.5 inches long. If you're looking at a 2D ultrasound picture, the baby often looks like a little gummy bear. You can clearly see the head, which is massive compared to the body right now because the brain is growing at an explosive rate. In fact, that tiny brain is producing about 250,000 new neurons every single minute.
You’ll also notice the limb buds have turned into actual arms and legs. They aren't just paddles anymore. If the technician gets the right angle, you can actually see tiny fingers and toes starting to separate. The "webbing" that was there a week ago is mostly gone.
Why the head looks so big
It’s honestly kind of funny looking. The head is nearly half the length of the entire body at this stage. Why? Because the central nervous system is the priority. When you see 10 weeks pregnant pictures of fetus from a side profile (the "nub" view), the forehead is very prominent and bulges out. This isn't a deformity; it’s just where all that brain power is being stored.

What’s happening under the skin?
If you could look past the skin—which is still very thin and see-through—you’d see bones starting to harden. This process is called ossification. Those tiny knees and elbows are forming joints.
The tail is gone.
Yeah, we all had tails for a minute there. By week 10, that embryonic tail at the bottom of the spinal cord has completely disappeared. In its place, the spine is becoming more defined. You can actually see the "pearl string" of the vertebrae on a high-resolution ultrasound.
The heart is also a powerhouse right now. It is fully formed and beating incredibly fast—usually between 140 and 170 beats per minute. That’s about twice as fast as your own heart. Hearing that "galloping horse" sound for the first time on a Doppler is usually the moment it feels real for most parents.
The "Gummy Bear" dance
One thing people don't expect when looking at 10 weeks pregnant pictures of fetus or watching a live scan is the movement.
They move. A lot.
Even though you can't feel it yet—you probably won't feel "quickening" until week 16 to 22—the fetus is doing little flips, jerky arm movements, and even starting to swallow amniotic fluid. According to the American College of Obstetricians and Gynecologists (ACOG), these movements are vital for muscle and joint development. If you catch a 10-week fetus on a 4D ultrasound, it looks like a tiny person dancing in a very cramped club.

Common misconceptions about 10-week visuals
I hear this all the time: "Can you tell the gender at 10 weeks?"
The short answer is: Not by looking at a picture.
While the external genitalia are starting to form, they look almost identical on an ultrasound at this stage. Both boys and girls have a small protrusion called a genital tubercle. It takes a few more weeks for the "angle of the dangle" (the nub theory) to become even remotely reliable.
However, you can find out the sex this week through a NIPT (Non-Invasive Prenatal Testing) blood test. It looks at the fetal DNA circulating in your blood. So, while the 10 weeks pregnant pictures of fetus won't tell you if it's a boy or a girl, a lab tech certainly can.
Another thing? The eyes. In pictures, you’ll see two dark spots on the side of the head. The eyelids are actually fully formed now, but they are fused shut. They won't open until around week 27. The ears are also very low on the head right now, looking a bit like little dips, but they’ll migrate up as the jaw develops.
Your body at 10 weeks: The container
While the fetus is busy growing fingers, you’re probably busy trying not to puke. Or maybe you're just exhausted.
Your uterus is now about the size of a large grapefruit. Before pregnancy, it was the size of a small pear. Because it’s expanding, it’s starting to push up out of your pelvis, which might mean you’re finally noticing a tiny bit of firm rounding just above your pubic bone.

- Visible Veins: You might notice blue maps appearing on your breasts or thighs. Your blood volume has increased by about 50% to support the baby, and your veins are working overtime.
- The "Glow" (or lack thereof): Some people get the clear skin. Others get "pregnancy acne" thanks to the surge in progesterone.
- Round Ligament Pain: You might feel a sharp "zing" if you sneeze or move too fast. Those are just the ligaments holding your uterus stretching out.
Is it a 10-week bump or just bloat?
Honestly? It's probably mostly bloat. Progesterone slows down your digestion to ensure the baby gets maximum nutrients, which leads to... well, gas. Lots of it. But hey, if you want to call it a baby bump, go for it. You’re 25% of the way through!
Practical next steps for week 10
If you are looking at 10 weeks pregnant pictures of fetus because you just had your first appointment, or you're preparing for one, here is what you actually need to do:
Book your NIPT screening. If you want to check for chromosomal abnormalities (like Down Syndrome) and find out the biological sex early, this is the window to do it. It's just a simple blood draw.
Buy a "transition" bra. Your ribcage is already starting to expand, and your breasts are likely heavy and sore. Don't wait for the third trimester to get comfortable. A seamless, wire-free bra will save your life right now.
Check your dental health. Strange but true—pregnancy gingivitis is a real thing. High hormone levels make your gums more susceptible to plaque and bleeding. Tell your dentist you're pregnant and get a cleaning.
Increase your fiber. Since we mentioned the bloat, start eating more raspberries, lentils, or chia seeds. It helps move things along when your digestive system is basically at a standstill.
Start a "bump" photo series. Even if you don't feel like you have a bump yet, take a photo in a specific outfit today. When you look back at these 10 weeks pregnant pictures of fetus and compare them to your 40-week belly, the transformation will blow your mind.
Keep in mind that every pregnancy is different. Some 10-week fetuses are slightly ahead in growth, some are right on the mark. If your ultrasound technician says the "crown-rump length" (CRL) is healthy, then your little kumquat is doing exactly what it needs to do.
