Question: 23 weeks how big is your uterus?
Answer: What changes are occurring with your body? Your uterus now extends about 1 ½ inch (3.8 cm) above your belly button, and your weight gain should be around 12 to 15 pounds (5.4 to 6.8 kg). Friends and family may comment on your size, telling you that you are too big or too small for your gestational age.
