Welcome to our week-by-week pregnancy guide! We’re here to share everything you need to know as you navigate this exciting journey— from symptoms to baby development, changes in your body, and what to expect at your upcoming appointments. Here’s what’s happening at week 13.
Your Body at 13 Weeks Pregnant
As you approach the second trimester, you might find that some uncomfortable symptoms are keeping you awake at night. For instance, pregnancy heartburn and indigestion can be frustrating, especially if you’ve recently indulged in marinara sauce with your pasta. This symptom can persist for some women and might worsen as your organs make room for your growing baby.
On the bright side, there are many positives to look forward to as you transition into the second trimester next week. Your risk of miscarriage will decrease, and the overwhelming fatigue you may have experienced in the early months should start to fade, giving way to a boost of energy just in time for you to prepare your home for the little one.
Stretch Marks
As your uterus expands and your breasts prepare for breastfeeding, you may start to notice pink or red stretch marks appearing on your abdomen, hips, thighs, and breasts. A study from 2016 found that over half of pregnant women develop stretch marks, and unfortunately, there are limited preventive measures since they are largely genetic. However, moisturizing your skin with cocoa butter can help improve elasticity, and remember that these marks tend to fade after childbirth.
Your Baby at 13 Weeks Pregnant
This week, your little one’s head, which has been the focus until now, will start to look more proportionate as the rest of the body catches up in growth. At 3¾ inches long and weighing 1¼ ounces, your baby is roughly the size of a buffalo chicken wing. All major organs are fully formed, and your baby is now actively taking in amniotic fluid and peeing it out—yes, this is just the beginning of them peeing on you!
In addition, your baby’s vocal cords are beginning to develop. Before long, you may hear those adorable little coos, perhaps just moments before they decide to throw food on the floor!
Symptoms and Health at 13 Weeks Pregnant
13-Week Ultrasound
During this week, your doctor will likely arrange a Nuchal Translucency ultrasound between 11 and 13 weeks and six days. This ultrasound, along with some blood tests, assesses your baby’s risk for chromosomal conditions such as Down syndrome and trisomy 18.
Cozying Up with a Pregnancy Body Pillow
If you haven’t embraced a pregnancy body pillow yet, now might be the time. As your body grows, sleeping on your left side is recommended for better circulation. A specially designed body pillow can provide support and alleviate some of the pressure on your hips and lower back.
Heartburn
Hopefully, by week 13, morning sickness is starting to ease, allowing you to enjoy food again. However, heartburn might be on the rise. This common pregnancy symptom, especially in the second and third trimesters, is due to hormones like progesterone that relax esophageal muscles, leading to acid reflux. To combat heartburn, try avoiding spicy or greasy foods, eating smaller meals throughout the day, and keeping your head elevated during sleep.
Clumsiness
Feeling a bit clumsy? You’re not alone. Many women experience this due to pregnancy hormones relaxing joints and ligaments, along with changes in weight distribution that can throw off balance. So, be cautious and alert, especially in slippery conditions.
Double Trouble
If you’re carrying twins or more, it’s essential to be proactive about your health. It’s recommended that all pregnant women take iron and folate supplements to prevent anemia, which is even more crucial for those expecting multiples. You can expect to gain more weight, too—think 40-50 pounds for twins instead of the usual 25-35 for a single baby. Balance healthy meals with those cravings to ensure both babies receive the nutrients they need.
