Welcome to the week-by-week pregnancy guide! As you reach the 20-week milestone, we’re here to provide insights on what to expect during this exciting time, including your baby’s growth, your body’s changes, and important appointments. Let’s dive into the details for week 20.
Your Body at 20 Weeks Pregnant
Halfway Mark
Congratulations! You’ve hit the halfway point of your pregnancy. By now, you might be feeling a surge of energy, enjoying your new maternity wardrobe, and delighting in the gentle movements of your baby, which you can now identify as kicks. Typically, you should expect to gain about half a pound weekly from this point forward, but don’t worry if it varies slightly—just consult your healthcare provider to ensure you’re on the right path.
If you haven’t begun to sleep predominantly on your left side, this is a vital week to start. Experts advise against sleeping on your back after this point, as the weight of your uterus can put pressure on the vena cava, a major blood vessel, potentially leading to dizziness and reduced blood flow to your baby.
What to Anticipate During Your 20-Week Anatomy Scan
This week is significant for several reasons: if you haven’t already learned your baby’s sex through the NIPT test, this is the week you’ll discover it. If you’d prefer to keep it a surprise, inform the technician before your appointment.
The anatomy scan, which lasts about two hours, will offer a closer look at your baby’s growth and development. The technician will examine key organs, including the heart, kidneys, bladder, and spine, and measure your baby’s body and head. Be sure to hydrate beforehand, as a full bladder can improve the clarity of the ultrasound.
Your Baby at Week 20
Size of a Slice of Pie
Your baby now weighs around 10 ounces and measures nearly 7 inches long, roughly the size of a slice of pumpkin pie. Interestingly, your little one is developing taste buds and may be able to experience flavors from foods you consume, such as garlic or spicy dishes.
If you’re expecting a boy, his testicles will begin to descend this week, and this should be visible during the scan. For a girl, her uterus and ovaries are developing rapidly, along with her vaginal canal.
Your baby is covered in a protective white substance known as vernix caseosa, which shields them from amniotic fluid and helps regulate their temperature. This week also marks the beginning of meconium production, the first poop your baby will pass after birth, composed of cells, mucus, and amniotic fluid.
Your Symptoms and Health at 20 Weeks Pregnant
Monitoring Blood Pressure
As your pregnancy progresses, it’s essential to watch for signs of preeclampsia. Symptoms may include swelling, severe headaches, vision disturbances, and pain under the ribs. If you notice any of these, reach out to your healthcare provider immediately.
Dizziness and Blood Volume
With your blood volume having doubled, your heart is under more strain, which may lead to low blood pressure and dizziness. When changing positions, do so slowly, and remain well-hydrated to avoid these symptoms.
Varicose Veins and Hemorrhoids
Hormonal changes and increased blood volume can lead to varicose veins, often appearing on the legs and buttocks. Elevating your feet, using compression stockings, staying hydrated, and maintaining an active lifestyle can help alleviate this discomfort.
Hemorrhoids, which are essentially varicose veins in the rectal area, may also occur due to increased pelvic pressure and constipation. Warm baths, witch hazel pads, and a fiber-rich diet can provide relief.
Double the Excitement
If you’re expecting twins, the anatomy scan will be particularly informative, revealing the genders if you haven’t already found out. This is also when your healthcare provider will check on the anatomy of both babies to ensure everything is developing properly. You may start to feel more consistent movements from your babies this week, which can sometimes feel like your stomach is just grumbling.
As your pregnancy progresses, expect regular scans every four weeks to monitor the growth of your twins.
