Welcome to Week 13—the start of the second trimester! 🎉 You’ve officially graduated from the toughest stage of early pregnancy. While baby is still small (about the size of a pear, around 3 inches long), they’re growing fast and starting to develop more distinct features and movements.
What’s Happening in Your Body?
Your baby’s bones are hardening, vocal cords are forming, and tiny fingerprints are already unique to them. Their body is starting to catch up with their head, which still makes up about half their size. Baby can even suck their thumb and wiggle around—though you still won’t feel those movements just yet.
For you, hormones are beginning to stabilize a bit. That often means less nausea, more energy, and a slight return to feeling human again.
Common Symptoms This Week
The second trimester is often called the “honeymoon phase” of pregnancy because things may ease up. You might notice:
Nausea fading (hallelujah!)
Energy returning—or at least improving
Mild round ligament pain as your uterus grows
A tiny bump becoming more noticeable
Increased appetite
Mood leveling out (though hormones are still doing their thing)
But remember, everyone’s timeline is different. If you’re still queasy or exhausted, you’re not “behind”—your body just needs more time.
What You Can Do This Week
Celebrate making it to the second trimester—this is a big deal!
Start thinking about maternity clothes if your jeans are feeling snug
Plan your next prenatal appointment and second-trimester screening tests
Begin a light exercise routine if you’re feeling up to it
Focus on balanced meals—your appetite may be coming back
This is also a good time to start journaling or tracking your pregnancy journey—even just a few notes in an app like Cubtale can be a beautiful keepsake for later.
Real Talk
Week 13 can feel like a breath of fresh air. You might finally be ready to share the news more widely, or you might still want to keep it close. Either choice is okay.
It’s also normal to feel a mix of relief and new worries—because with every milestone comes a new set of questions. Just know this: you’ve already made it through some of the hardest weeks, and you’re stronger than you probably give yourself credit for.
The second trimester is often when the joy starts to peek through the fog. Let yourself enjoy it, even if it feels scary to.
