Welcome to your week-by-week pregnancy guide! Here’s everything you need to know about your 21st week of pregnancy, including what to expect for both you and your baby.
Your Body at 21 Weeks Pregnant
At this stage, you are cruising through the second trimester, having gained around 13 to 15 pounds. However, remember that every pregnancy is unique, and weight gain can vary. Moderate exercise is recommended to help manage potential gestational diabetes, reduce swelling, and improve circulation. Always check with your healthcare provider before starting any new exercise routines.
Nesting Instincts
The second trimester often brings a surge of energy and a desire to prepare for your little one. This is a prime time for cleaning and organizing as the nesting instinct kicks in. Interestingly, women expecting during late spring and summer may feel this urge more strongly, coinciding with the natural inclination to spring clean. It’s a great moment to set up the nursery, create your baby registry, and even plan a well-deserved babymoon. After all that preparation, you’ll definitely need some rest and relaxation.
Your Baby’s Development at Week 21
At 21 weeks, your baby measures about 10.5 inches long and weighs approximately 11 ounces, roughly the size of a bread bowl. They are developing regular sleep cycles and will spend around 90 percent of their time sleeping, much like a newborn. Beneath the surface, your baby is practicing essential skills like breathing, swallowing, and kicking. Remarkably, they can even taste the foods you eat, including that spicy taco you had last night!
This week also marks the completion of eyelid formation, production of meconium, and the development of their senses, including responsiveness to touch. Gently pressing on your belly might even prompt a little kick or “high-five” in return.
Symptoms to Expect at Week 21
- Braxton Hicks Contractions: You might notice these practice contractions more frequently. If they’re not severe or regular, there’s usually no cause for concern. However, if you experience painful or persistent contractions, reach out to your doctor, as it could indicate preterm labor.
- Breast Changes: By now, your breasts may be fuller and larger in preparation for breastfeeding, potentially increasing by up to a cup and a half by delivery.
- Aches and Pains: As your baby grows, you may experience some aches due to the changes in your body’s weight distribution. The hormone relaxin helps to loosen joints and ligaments, which can lead to back or joint discomfort. Incorporating stretches, staying active, using a belly support band, and maintaining good posture can help alleviate some of this discomfort.
- Heartburn: With your appetite returning, you may find heartburn becoming a common issue due to hormonal changes that affect digestion. To ease this symptom, consider avoiding spicy or greasy foods, eating smaller meals, and keeping your head elevated while sleeping.
- Headaches: Increased blood volume can lead to headaches for some women during this stage. Factors like dehydration, posture, and caffeine withdrawal may contribute. If headaches persist, consult your OB before taking any medication. Be vigilant for severe headaches, especially later in your pregnancy, as they may indicate high blood pressure or preeclampsia.
For Those Expecting Twins
If you’re carrying twins, Braxton Hicks contractions may be more pronounced. Keep an eye on their severity and frequency, and consult your healthcare provider if you’re concerned, as twins are at a higher risk for premature labor.

Summary
At 21 weeks pregnant, your baby is developing rapidly and is about the size of a bread bowl. Your body is adapting to these changes, and while you may experience some common symptoms, it’s essential to stay informed and consult your healthcare provider with any concerns.
