Week 12

You made it—Week 12 marks the final week of the first trimester. 🎉 Your little one is now about the size of a lime (around 2 inches long) and officially looking more like a tiny baby than ever. And for many, this is the week when pregnancy starts to feel a little less secret, a little more real.

What’s Happening in Your Body?

Your baby’s vital organs are fully formed and starting to function. Reflexes are developing—your little one can open and close their fingers, curl their toes, and even make tiny sucking movements. Their face now has a profile with a nose and chin, and their heartbeat is strong and steady.

For you, hormone levels are still high, but they’re about to level out soon—meaning some of those intense symptoms may start to ease.

Common Symptoms This Week

• Nausea and fatigue might finally begin to improve (but don’t worry if they haven’t yet)

• Bloating and mild round ligament pain as your uterus continues to expand

• Mood swings (yes, still!)

• Headaches or dizziness from increased blood flow

• Visible veins and fuller breasts

• Maybe a tiny baby bump starting to show, especially if this isn’t your first pregnancy

And some people start noticing a bit more energy creeping back—like a faint promise of the second trimester glow.

What You Can Do This Week

• Attend your first ultrasound if you haven’t yet—this is often when you’ll see your baby’s shape clearly for the first time

• Ask your provider about any genetic screenings you’re considering (like nuchal translucency or NIPT)

• Start thinking about how you want to share the news, if you haven’t already—many people feel more comfortable announcing after the first trimester

• Begin light prenatal exercise if you’re feeling up to it—walking, swimming, or yoga can help

And of course, keep tracking how you feel. It’s helpful to see what’s changing over time—something Cubtale makes simple, even in these early stages.

Real Talk

Reaching Week 12 is a milestone. You’ve been through weeks of nausea, exhaustion, and “is this normal?” Googling. Maybe you’re starting to breathe a little easier. Maybe you’re still anxious. Maybe both.

Whatever you’re feeling, you’re not alone. The first trimester can feel like a lonely marathon—but you’ve done it. And the next stage? It’s usually a lot kinder.

Take a deep breath. You’re stepping into a new chapter—one where you might finally feel a bit more like you again.
