Pregnancy Weeks 10-14: Finally, the Second Trimester!

Watch the original video from BabyCenter — it's so worth it!

By Rahimibu | Reading time: 4 minutes

If the last few weeks were all about nausea and exhaustion, now you can finally breathe a little. Welcome to the edge of the second trimester! This is when morning sickness usually starts to fade and energy slowly comes back. But while you're enjoying feeling human again, inside your uterus, your little one is busy transforming.

Based on the amazing BabyCenter video (I put it up there—go watch it!), here's what's happening during weeks 10 to 14. Spoiler: from kumquat to tiny human in just a few weeks.

Weeks 10-12: From Tiny Fruit to Tiny Human

By week 10, your baby is about the size of a kumquat. Small, but don't underestimate this phase! This is when they officially stop being an embryo and become a fetus. Facial features are getting clearer, and believe it or not, the buds for baby teeth are already forming under those tiny gums.

Here's the mind-blowing part: the webbing between their fingers and toes is completely gone, replaced by tiny nails and unique fingerprints that they'll have for life. You can't feel it yet, but they're already moving around in there—little stretches, little kicks. Showing off, basically.

Weeks 13-14: Kidneys Online & Facial Expressions

Around week 12, something new starts working: the kidneys. They begin producing urine, which goes into the amniotic fluid. Sounds weird, right? But your baby will swallow that fluid, and the cycle repeats. It's all part of their development—getting ready for life outside.

By week 14, the eyes and ears have moved to their correct positions. And here's the cute part: your baby can now make facial expressions. Frowning. Squinting. Grimacing. They're practicing for all the faces they'll make at you later.

And just like that, you're in the second trimester. The "honeymoon phase" of pregnancy, they call it. The nausea lifts, the bump starts showing, and you finally feel like yourself again—just with a tiny human practicing frowns inside you.

I don't know about you, but learning this made me appreciate the second trimester so much more. It's not just a break from feeling sick—it's when your baby becomes more. More human. More expressive. More ready to meet you.
