10 Weeks Pregnant: Week-by-Week Guide

10 Weeks Pregnant: Week-by-Week Guide

Congratulations! You’re at the 10-week pregnancy mark. There are so many new and incredible developments and discoveries at this stage of your journey. Check out this week-by-week guide to find out what’s in store for your baby and your body in week 10 of pregnancy.

  • 10 weeks pregnant is which trimester? First trimester
  • How many weeks of pregnancy are left? 30 weeks
  • 10 weeks pregnant is how many months? You’re in your third month. 

With week nine of your pregnancy complete, you’re on week 10. Enjoy it, as week 11 is on the horizon! 

One of the most exciting things about pregnancy is how many changes you’ll experience with your little one over the span of just seven days! Here are some tips and tricks to keep on top of all that’s happening.

Your baby at 10 weeks pregnant

What’s happening in there

  • Your baby is the size of a prune.
  • Your baby is transitioning from an embryo to a fetus. At 10 weeks, your little seed is growing fast.
  • It’s three months in nowthat’s six more to go!

10 weeks: baby development

  • That sweet face: Their cute-as-a-button face is forming from today on. Their eyes will stay shut for protection until around week 26.
  • All smiles: There’s so much happening right now that you can’t see. Your baby’s future toothy grin is forming below the gum line, though it won’t be making an appearance until your baby is around six months old.
  • Things are coming along nicely: That little tummy is becoming active, producing digestive juices. The vital organs have formed, and the kidneys are producing larger amounts of urine (though nothing like what you’ll be dealing with once you finally meet). In the case of boys, they’re already producing testosterone.
  • Not to get a big head: Your little one’s brain now accounts for 43% of their weight! In week 10, the hypothalamus forms. That’s the control center for systems like regulating body temperature and heart rate.

What should I be feeling at 10 weeks pregnant?

  • Feeling happy, sad, indifferent, furious? You’ll be having mood swings you haven’t experienced this side of puberty. It’s part of the rollercoaster ride fueled by all those changing hormones.
  • Since there are a lot of changes, things like smells can set your body off. Some of the scents you grew up loving may become a source of revulsion.
  • Nausea and vomiting can still be part of your reality at this point, along with constipation and flatulence—all the fun things.
  • You’ll want to get that camera out and capture your first baby belly shots, as your little bump is finally growing!
  • Each day you should fill up on a healthy breakfast. Oatmeal and DHA-enriched eggs can fill you with low calories and high protein, and DHA is an essential nutrient for baby’s brain development and eye formation.

Week 10 pregnancy symptoms

During week 10 of pregnancy, your body is changing quickly. As your baby grows, you will too, and there are certain pregnancy symptoms you may experience at this time.

9 common week 10 pregnancy symptoms

  1. That sluggish intestinal system you’ve been used to will probably stick around a while longer, so have plenty of healthy whole grains, fruits and veggies, and lots of water to offset the sluggishness and constipation. Try to keep up with a regular aerobic exercise routine as well.
  2. Your fatigue levels probably feel at an all-time high (or is that low?). As your body is doubling down on its essential services to pump life into the tiny version of you in your uterus, week 10 will ensure you know all about it. Though it may sound strange, you will feel better after going for a walk or doing some level of exercise.
  3. You may still be experiencing nausea and vomiting. Ginger supplements can help. You might also be craving sweet things like chocolate brownies. A little is OK, but be careful not to overindulge (at this stage).
  4. Heartburn and indigestion are common symptoms. Sleep with your feet up on a pillow to elevate your legs.
  5. You can become a wind farm, as flatulence can and will happen. Warn your partner (or put the blame on them).
  6. You may experience ligament pain as your body evolves into mom mode. Your uterus is stretching to make room for its needy house guest. Take time to get off your feet and make yourself comfortable.
  7. Skyrocketing hormones can cause headaches, especially during your first trimester. 
  8. Those pregnancy hormones are also to blame for mood swings. 
  9. You might begin noticing a network of visible blue or purple veins throughout your body due to increased blood flow.

That belly bump is getting closer. The uterus at 10 weeks pregnant is about the size of a large orange, so you may just be starting to show. 

2 tips for week 10 for a healthy and safe pregnancy

Being 10 weeks pregnant is an important time for you and your baby. Here are some tips on how to adjust to this new stage to keep you and your baby safe.

  • Work it out: Aim for 30 minutes of daily exercise at this stage. If you’re having trouble maintaining your regular exercise routine, consider adding yoga (with your doctor’s approval). It can help you get a better night’s sleep, ease pregnancy-related symptoms, and even prep you with breathing techniques you can use during labor.
  • A lot is happening in there: The end of week 10 marks the point when your baby transitions from an embryo to a fetus. The embryonic stem cells have multiplied and formed into the basis of the internal and external body structure. Keep eating healthy meals and taking a prenatal multivitamin containing DHA, as it’s one of the major building blocks of your baby’s brain, bones, and vision.
