Welcome to the last month of your first trimester. Woo-hoo! If you’ve been through the wringer with morning sickness (or all-day sickness), fatigue, and emotional highs and lows, you will be thrilled to move into your second trimester. Things do get better! By Week 9, your baby is the size of grape. In Week 10, he or she officially goes from an embryo to a fetus. Congrats! And, by Week 13, your gorgeous baby has grown to the size of a nectarine, about 3 inches long.
• In Week 9, your baby’s head continues to develop as his or her beautiful face is rounding. Muscles take form, all major limbs and joints (such as the shoulders, elbows, wrists, knees, and ankles) are working. The heart has evolved into four chambers. The valves are forming. Your baby’s external sex organs are developing, but they are not visible yet. You might hear a heartbeat, but that usually happens the following week.
• In Week 10, tooth buds materialize, your baby’s stomach begin to produce digestive juices, and his or her kidneys can start to produce urine. Eyelids are more developed. The ears and external features are almost formed. Your baby’s heartbeat might be heard. Exciting!
• In Week 11, your baby’s body is straightening. His or her skin is transparent. Hair follicles are forming. Fingers and toes have separated, and nail beds begin to appear. Tiny tooth buds form below the gums. The placenta begins to function. This amazing organ provides oxygen and nutrients to your baby.
• In Week 12, your baby’s bone marrow produces white blood cells. The pituitary gland begins to produce hormones. The intestines, which have been developing outside of the baby, now have moved back into the abdomen.
• In Week 13, your baby’s brain continues to develop rapidly. Vocal cords are being primed to make that first cry. Fingerprints are developed.
Your body will experience changes similar to those in Month 2. Fatigue and sleepiness might continue to be your middle name. Some women may have nausea, bloating, gas, constipation, heartburn, indigestion, food aversions and cravings, sensitivity to smell, and the frequent need to pee. Headaches are common. Some bellies begin to get rounder about now. Breast fullness and heaviness is common. Tenderness, tingling, and darkening areolas might occur now, or at any time during pregnancy. Blood volume increases, giving some women that “glow.”
Your nutrition focus is foods to enhance your baby’s cell, brain, eye, bone, and teeth development. The following nutrients will help achieve this.
• B vitamins: cell division, brain formation, nervous system development, morning sickness
• Calcium: bones and teeth
• Magnesium: bones and muscle development
• Manganese: bone development and nerve health
• Omega-3s: brain, eye, and nervous system development
• Phosphorus: genetic material
• Potassium: nerve and muscle function
• Vitamin A: cell structure, bones, teeth, nervous system
• Vitamin C: iron absorption, healthy teeth and gums, immunity
• Vitamin D: calcium absorption
• Vitamin E: cell structure and genetic material
• Vitamin K: bone mineralization
• Zinc: cell structure and genetic material
