Welcome to the week-by-week guide for expecting parents! At 20 weeks pregnant, you’re officially at the halfway mark of your pregnancy journey. This week brings exciting developments for both you and your baby, so let’s delve into what you can expect.
Your Body at 20 Weeks Pregnant
Halfway There!
Congratulations! You’ve reached the halfway point of your pregnancy. By now, many expectant mothers report feeling more energetic and enjoying their growing collection of comfortable maternity wear. You might also start noticing those tiny fluttering movements that signal your baby is active. From this week forward, you can anticipate gaining about half a pound each week. However, it’s important not to stress if the numbers fluctuate—as long as your healthcare provider gives you the green light.
If you haven’t already begun to sleep primarily on your left side, now is the time to make that adjustment. Medical experts advise against sleeping on your back from this point onward, as the weight of your uterus can press against the vena cava, a critical blood vessel. This pressure can lead to dizziness, nausea, and reduced blood flow to your baby.
What to Expect During Your 20-Week Anatomy Scan
This week is significant for several reasons. If you haven’t yet learned your baby’s sex through a non-invasive prenatal test (NIPT), the anatomy scan provides a great opportunity. If you prefer to keep it a surprise, just inform the technician before the scan begins.
The two-hour anatomy scan serves to closely monitor your baby’s growth and development, focusing on vital organs such as the heart, kidneys, and bladder, as well as the spine and stomach. Be sure to hydrate before the exam, as a full bladder helps produce clearer ultrasound images.
Your Baby at 20 Weeks Pregnant
A Slice of Pumpkin Pie
At this stage, your baby weighs about 10 ounces and measures nearly 7 inches long—roughly the size of a slice of pumpkin pie. Interestingly, your baby is now developing taste buds and may even be able to experience flavors from your diet, including strong ones like garlic or spicy foods.
For those expecting boys, this week marks the descent of the testicles, which should be visible during the anatomy scan. Meanwhile, girls are experiencing rapid development of their ovaries, uterus, and vaginal canal.
Additionally, your baby is now covered in vernix caseosa, a creamy substance that protects them from the amniotic fluid and helps regulate their temperature. This week also heralds the production of meconium, the first poop composed of cells, lanugo, mucus, and amniotic fluid, which your baby will pass after birth.
Symptoms and Health Considerations at 20 Weeks Pregnant
Monitoring for Preeclampsia
As your pregnancy progresses, it’s crucial to stay vigilant for signs of preeclampsia. Symptoms may include swelling, severe headaches, vision changes, and pain below the ribs. If you experience any of these, consult your healthcare provider immediately.
Dizziness and Blood Pressure
With your blood volume having doubled, your heart is working harder than ever. This can lead to low blood pressure, resulting in dizziness. Be sure to rise slowly from sitting or lying positions, and stay well-hydrated to help prevent these symptoms.
Varicose Veins and Hemorrhoids
Hormonal changes and increased blood volume can lead to varicose veins, often appearing in the legs, buttocks, or vaginal area. Elevating your feet, wearing compression stockings, and staying active can help improve circulation. Hemorrhoids, which are a form of varicose veins in the rectum, can also occur, often exacerbated by constipation. Warm baths, witch hazel pads, and a fiber-rich diet can alleviate discomfort.
Expecting Twins?
If you’re carrying multiples, the anatomy scan will be especially important this week. This scan often reveals the genders of your babies (if not already known) and provides a comprehensive check on their anatomical development. Expect to feel more fetal movements, which can sometimes be mistaken for stomach growling, especially if this is your first pregnancy. From this week on, twin scans will occur every four weeks to monitor growth.
