Congratulations on your pregnancy! The third trimester typically begins around week 28 of pregnancy. However, it's important to note that every pregnancy is different, so the exact timing may vary for each individual. The third trimester is an exciting time as your baby continues to grow and develop rapidly. During this stage, you may experience new symptoms such as increased fatigue, back pain, frequent urination, and Braxton Hicks contractions. It's essential to continue regular prenatal check-ups with your healthcare provider during this period to monitor both your health and the baby's progress. If you have any concerns or questions about your specific situation, it's always best to consult with your healthcare provider for personalized advice and guidance.
