Your baby this week
Your baby is about the size of a mango, measuring around 6 inches and weighing about 8.5 ounces. A waxy, cheese-like coating called vernix caseosa is forming over baby's skin to protect it from the amniotic fluid — without it, baby would look very wrinkled at birth from months of soaking. All five senses — sight, hearing, smell, taste, and touch — are developing rapidly as specialized areas of the brain designate for each. Baby's arms and legs are now proportional to the rest of the body. The kidneys are producing urine, and hair is beginning to sprout on baby's scalp.
How you may feel
Hip pain becomes more common as your pelvis gradually widens and ligaments loosen in preparation for delivery. Leg cramps, especially at night, can be painful and disruptive to sleep — they're thought to be caused by the extra weight you're carrying, changes in circulation, and possibly low levels of calcium or magnesium. You may notice your belly growing more rapidly now, and the fundus (top of the uterus) is near your belly button. Skin changes like chloasma (dark patches on the face, also called the "mask of pregnancy") may appear due to increased melanin. Round ligament pain may continue as your uterus grows and the supporting ligaments stretch.
Common symptoms
- Leg cramps, especially at night, become more common as the uterus presses on nerves.
- Skin darkening (melasma or "mask of pregnancy") may appear on your face.
- Hip pain during sleep as ligaments loosen in preparation for birth.
This week's tips
To help prevent and relieve leg cramps, stretch your calves before bed by flexing your feet (pulling toes toward your shin), and eat potassium-rich foods like bananas, sweet potatoes, and avocados. Magnesium-rich foods such as almonds, dark chocolate, and spinach may also help reduce cramping. Stay well-hydrated throughout the day, as dehydration can worsen muscle cramps. If you experience hip pain, try sleeping with a pillow between your knees and consider a prenatal support belt for daytime wear. Apply SPF 30+ sunscreen daily to help prevent or minimize chloasma, which can worsen with sun exposure.
Eating well
- Eat magnesium-rich foods — dark chocolate, almonds, and spinach — to reduce leg cramps.
- Include vitamin E-rich foods like sunflower seeds and avocados for skin health.
- Stay hydrated with at least 10 cups of water per day to reduce muscle cramps.
Nutrition focus
- Magnesium (350 mg/day) and potassium-rich foods are your allies against cramps.
- Vitamin E (15 mg/day) supports healthy skin — found in nuts and wheat germ.
Everyday wellbeing
- Stretch your calves before bed — flex your foot toward your shin to prevent cramps.
- Wear sunscreen (SPF 30+) daily to minimize melasma darkening.
- Use a pillow between your knees when sleeping on your side to ease hip pain.
For your partner
If she gets leg cramps at night, you can help by gently flexing her foot (pushing toes toward the shin) and massaging the calf muscle until the cramp releases — this provides much faster relief than waiting it out. Keep a heating pad or warm towel nearby for quick application to cramping muscles. During the day, encourage her to stay hydrated by keeping a water bottle filled and within reach. Start discussing the nursery setup — choosing paint colors, furniture layout, and a theme can be a fun project to work on together during these middle months of pregnancy.
Signs to mention to your provider
- Leg cramps that don't resolve, with redness and warmth, may indicate a blood clot.
- Sudden vision changes, spots, or flashing lights need urgent evaluation.
- Contractions occurring regularly before week 37 are a sign of preterm labor.
