The third trimester begins in week 29 of pregnancy and lasts until the birth of your baby, typically around week 40. However, it's common for labor to start a few weeks before or after the due date.

During the third trimester, prenatal visits become more frequent, usually every two weeks, to closely monitor your health and the baby's development. These visits may include checking your weight, blood pressure, urine, and the baby's position and heart rate. Discussing labor and delivery plans with your healthcare provider is also a good time.

Expect to experience increased body heat, more frequent urination, swelling in your ankles, hands, and face, and changes in hair growth. You may also notice more pronounced backaches, shortness of breath, and heartburn as your baby grows.

Preparing for labor involves attending childbirth classes, creating a birth plan, discussing pain management options, and packing a hospital bag. It's also helpful to review your birth plan with your healthcare provider and keep an open mind, as plans may need to change.

Signs of labor can include regular contractions, water breaking, back pain, and pelvic pressure. If you notice these signs or are unsure, contact your healthcare provider for guidance.

In the third trimester, your baby will continue to grow in size and weight. The lungs, brain, kidneys, and bones will mature, and the baby will start to move into the birth position. Babies also develop the ability to see, hear, suck their thumb, and even cry.

Managing discomforts can include practicing good posture, wearing supportive shoes, staying active with safe exercises, using pillows for support while sleeping, and eating smaller, more frequent meals to help with heartburn. Always consult with your healthcare provider for personalized advice.

Keeping track of your baby's movements is important. You should feel regular movement, especially after meals or when resting. If you notice a decrease in movement or something doesn't feel right, contact your healthcare provider immediately.

Red flag symptoms include severe abdominal pain or cramps, heavy or continuous bleeding, severe dizziness, or persistent severe nausea and vomiting. If you experience any of these symptoms, seek medical attention right away.
