More information about 31 weeks pregnant

At 31 weeks pregnant, your baby weighs about 1.502 kg and is 41.1 cm long, and is running out of space inside mom’s belly. As space gets tighter, your baby’s movements may decrease and become more uncomfortable for you.

Baby’s Development

With longer arms and legs, the baby is more proportional to the trunk and head. If you have an ultrasound at this stage, it’s quite likely you’ll see your baby sleeping. They love to sleep now, warm and snuggled inside the safety of your womb. It’s also possible to hear their heartbeat, which is their favorite sound1!

31 semanas de gestaçãoAt this stage of the 31st week of pregnancy, the baby is more “alert” and already responds to external stimuli, such as the parents’ voices and caresses on your belly. This brings a lot of joy and excitement to your family as you watch your baby move when called. At 31 weeks, the lungs are almost ready2 and surfactant production is beginning. This substance prevents the walls of the air sacs from sticking together and making breathing difficult.

Watching your baby yawn is such a joy, isn’t it? Imagine seeing your baby do this during an ultrasound! At this stage, they usually sleep a lot and yawn frequently. You may even catch a glimpse of this on the ultrasound exam. Your baby at 31 weeks is pretty big now, about 41.1 cm long and weighing from 1.502 up to 2 kg.

Fat accumulates more noticeably under the skin, which prevents the blood vessels from appearing as prominently and clearly as before. You’re on the home stretch, there’s very little left for your baby to finish developing and be ready to come into the world. Get ready for lots of emotions!

How the mom is feeling

You’re almost halfway through the 3rd trimester! Now with your belly very noticeable, it’s very satisfying for you to walk around, proud. But even a simple stroll can become tiring. Swelling in the legs is common3, but should be monitored by your doctor. Blood pressure also needs to be checked regularly.

Mom’s Care

The incidence of pre-eclampsia has been increasing, sometimes due to poor diet during pregnancy. But with so much fast food and frozen meals available, it’s hard to eat well in the rush of the day. Too much salt becomes an enemy. That’s why having a healthy, balanced diet with lots of vegetables, greens, fruits, and natural juices is so good for mom and baby.

At this stage your breasts will be even larger, the areolas even darker, and some lumps may appear around the breast. These are signs that your breasts are preparing for breastfeeding and are part of the milk production process.

The area will also be more sensitive, so wear more comfortable bras at this stage. Your belly is huge and a dark line might be dividing your abdomen in half! This is the linea nigra, which will remain for a few months after pregnancy. But don’t worry, it will disappear just like it appeared!

External Factors

Sleeping is getting harder, isn’t it? There’s no comfortable position and when you finally find one, something starts to hurt or breathing gets more difficult. Try lying on your left side with a pillow between your legs, which will help you relax and get more comfortable. If you’re feeling anxious, drink a good cup of passionflower tea before bed. It will help you relax and allow you to sleep more peacefully.
