Baby:
Your baby is now about the weight of a cup of milk.
He’s still growing fast, and more and more bones are forming. Interesting fact: A newborn baby has 300 bones – but an adult only has 206 bones. The reason? Some bones fuse together as a child matures.
Another significant development is the formation of myelin, an important protective sheath around the nerves.
Mom:
Ah, another week, another strange new symptom. If you notice a short, intense pain in your lower abdomen, on one side of your groin or both sides simultaneously – one that’s accompanied by no other symptoms and usually goes away pretty quickly – you may be experiencing round ligament pain. (Though if you do experience other symptoms, or if the pain doesn’t subside on its own, call your doctor.)
Rough ligament pain may hit you all of a sudden, especially if you quickly get out of bed or turn suddenly, or if you cough or sneeze. But round ligament pain is nothing to be concerned about; as your uterus grows, the ligaments that connect it to your pelvis are growing right along with it, and that stretching can be uncomfortable.
Try gently shifting positions or leaning your body forward to help ease the pain. A warm compress can also sometimes help.
