More information about 38 Weeks Pregnant
At 38 weeks pregnant, your baby has vernix, that layer of fat that covers their whole little body and is now starting to decrease. However, they will probably still be born with traces of it, but far less compared to earlier. If your baby hasn’t been born yet, it’s just a matter of time before you meet them!
Your baby’s movements are less and less frequent and more limited because of their size inside the uterus1, but it is still normal for you to feel them move about 10 times throughout the day. If you go a long time without feeling them, contact your doctor for a checkup and a cardiotocography to analyze the baby’s heartbeat.
This week, your baby measures about 49.8 cm and weighs on average 3 kg. The longer they stay in the uterus, the more weight they will gain— as long as the placenta is still healthy and nourishing them as it should2. This process starts to slow down as labor approaches, when the placenta matures toward the end of pregnancy.
How Mom is Feeling…
Anxiety is running high waiting for the big day!!! Back pain is intense, physical fatigue is great and many women suffer from swelling at this final stage of 38 weeks pregnant. Practice contractions are common at this phase and the tightening of the belly can be uncomfortable and frightening for first-time moms!
To help with anxiety and make time pass quicker and more productively, make the most of these last moments with your bump to put the finishing touches on your baby’s room and check if everything is ready, as well as take care of yourself. Going to a beauty salon can help boost your self-esteem and help you get ready to look your best on your baby’s birth day.
If you still haven’t done the group B strep test during pregnancy3, the 38th week of pregnancy is a good time to do it, since in some cases, treatment for a positive test involves an antibiotic dose the day before labor to avoid contamination of the baby.
Difficulty sleeping, frequent urination, acne, swelling—all of this will pass, and it will all be worth it after the baby is born. Contractions are visible and may become increasingly frequent now, just pay attention to pain that is not normal, abnormal colored discharge and, speaking of which, do you know what the mucus plug looks like? It’s also normal to feel pain in your lower belly, but pay attention to these pains, since a urinary infection can be harmful and can occur at any stage of pregnancy.
Kicks and pokes are frequent, but as labor approaches, your baby seems to get quieter. Don’t worry, it’s due to the lack of space in the uterus. The famous belly waves are much more evident these two weeks. Take the opportunity to film them as a keepsake to show your child when they’re grown! It’s a unique and unforgettable moment.
External Factors…
My God, so much anxiety!!! We even start to imagine symptoms, which drives us crazy thinking that it’s finally time, right? We get so worried thinking we won’t know when we’re really in labor that we want to go to the hospital at any sign just to make sure all is well. But believe me—when you are in active labor you will know, it’s unlike anything else you’ve ever experienced!!
