Welcome to your week-by-week pregnancy guide! We’re here to provide you with all the essential information about what to expect during this journey—from your baby’s growth and your body’s changes to ultrasounds and appointments. Here’s the scoop on week 20.
Your Body at 20 Weeks Pregnant: Halfway There
Congratulations, you’ve reached the halfway point of your pregnancy! By now, you might be feeling more energetic and embracing the comfort of your new maternity wardrobe. Those little flutters you feel are likely your baby’s kicks, adding to the excitement. From this week forward, you should aim to gain about half a pound weekly. Don’t worry if it fluctuates a bit; just ensure your healthcare provider says you’re on track.
If you haven’t already started sleeping on your left side, now is the time to make that switch. Experts advise against back sleeping after 20 weeks, as the weight of the uterus can compress the vena cava, leading to dizziness, nausea, and reduced blood flow to your baby.
What’s Happening at Your 20-Week Anatomy Scan
This week is significant for multiple reasons. If you opted for the NIPT test, this is when you’ll discover your baby’s sex—if you want to keep it a surprise, just let the technician know before starting. The two-hour anatomy scan will closely observe your baby’s growth, focusing on vital organs like the heart, kidneys, bladder, spine, and stomach. Be sure to hydrate beforehand, as a full bladder helps improve ultrasound clarity.
Your Baby at 20 Weeks Pregnant: The Size of Pumpkin Pie
Weighing in at around 10 ounces and measuring nearly 7 inches, your baby is now about the size of a slice of pumpkin pie. Excitingly, they are developing taste buds and might even experience flavors from your meals, such as garlic or spicy foods.
If you’re having a boy, his testicles will begin to descend around this time, while a girl’s uterus and ovaries are maturing rapidly, along with her vaginal canal. Your baby is also coated in a protective white substance called vernix caseosa, which guards against amniotic fluid and helps regulate temperature. This week also marks the production of meconium, the first poop composed of everything your baby has ingested in utero, which they will pass after birth.
Your Symptoms and Health at 20 Weeks Pregnant: Keep an Eye Out
At this stage, both you and your healthcare provider should be vigilant for signs of preeclampsia. Symptoms can include swelling, severe headaches, visual disturbances, and rib pain. If you notice any of these, reach out to your doctor immediately.
Dizziness may also occur due to increased blood volume and changes in your cardiovascular system. Move slowly from sitting or lying positions to standing to avoid faintness. Staying hydrated is crucial, as dehydration can worsen these symptoms.
Hormonal shifts and increased blood volume may lead to varicose veins, appearing mainly in the legs, buttocks, and vaginal area. Elevating your feet, wearing compression stockings, staying hydrated, and remaining active can help improve circulation.
Hemorrhoids can also develop, often alongside constipation. Increased pelvic pressure and prolonged standing can exacerbate this issue. Warm baths, witch hazel pads, and a fiber-rich diet can alleviate discomfort.
If you’re expecting twins, this week’s scan may reveal their genders for the first time—if you didn’t choose the NIPT option. The anatomy check will ensure both babies are developing as they should. You’ll likely notice more movement now, although first-time moms might mistake the sensations for just stomach gurgling.
From here on out, scans for your twins will occur every four weeks to monitor their growth.
