So, THIS Is What’s Going On In My Belly
Week Thirty: Baby puts on pounds
|You are 30 weeks pregnant. (fetal age 28 weeks)
For several months, the umbilical cord has been the baby’s lifeline to the mother. Nourishment is transferred from the mothers blood, through the placenta, and into the umbilical cord to the fetus. Their bone marrow is now responsible for red cell production. These red blood cells will continue to service your child’s body by transporting oxygen and removing the wastes. Your baby begins storing iron, calcium and phosphorus.
The fetus now weighs about 3 pounds (1.4kg). He or she will gain about half a pound a week until week 38. Baby is getting fatter and beginning to control its own body temperature. Baby continues to put on fat stores and the major weight gains will occur in the coming weeks. Eyebrows and eyelashes are fully developed, and hair on the head is getting thicker. Head and body are now proportioned like a newborn.
Hands are now fully formed and fingernails are growing. Can be seen on ultrasound scans grasping their other hand or feet, this is helping with nerve development. Eyelids are opening and closing, and will often make rapid eye movements – a sign they could be dreaming.
You may be starting to experience some swelling of your ankles and legs. If you have not experienced any swelling yet, it is highly probable that you will, as approximately 40 to 75 percent of women will experience mild swelling related to pregnancy.
Your uterus is now about 4 inches (10cm) above your bellybutton. It may feel like you are running out of room as your uterus grows up under your ribs. However, your fetus, placenta and uterus will continue to get larger, you still have 10 weeks to go. The average weight gain during pregnancy is 25 to 35 pounds (11.5 to 16kg). About half of this weight is concentrated in the growth of the uterus, the placenta, the baby and in the volume of amniotic fluid. At this point, you should be gaining about a pound (500 grams) a week.
