The 40th week of pregnancy is an exciting and highly anticipated milestone for expectant mothers. At this stage, the baby is considered full-term and is ready to meet the world. In this article, we will guide you through what to expect during the 40th week of pregnancy, including fetal development, labor readiness, and tips for preparing for the arrival of your baby.
Fetal Development at 40 Weeks
At 40 weeks pregnant, your baby is approximately 20 inches (50 cm) long and weighs around 7.5 pounds (3.4 kg). The baby's skin is now smooth and plump, and the lungs are fully developed and ready for life outside the womb. The baby's digestive system is also mature, and they are able to digest food and absorb nutrients on their own.
The baby's brain and nervous system are fully developed, and they are able to control their body temperature, heart rate, and breathing. The baby's skeleton has changed from soft cartilage to bone, and their nails, hair, and eyelashes are fully formed.
Physical Changes in the Mother
At 40 weeks pregnant, you may be experiencing a range of physical symptoms, including back pain, pelvic pressure, and Braxton Hicks contractions. Your cervix may be dilating, and you may notice a bloody show or a mucous plug discharge.
Your belly may feel hard and tight, and you may experience frequent urination due to the pressure on your bladder. You may also experience mood swings, fatigue, and difficulty sleeping.
