Your baby now weighs over 5.5 pounds and its crown-to-rump length is approximately 13.2 inches. Your baby's total length is around 20.25 inches at this point. Your uterus is now 6 inches from the bellybutton and the average weight gain is approximately 24 to 29 pounds. Most pregnant women begin to feel cramped and heavy around this time and often become tired of being pregnant. Some women feel like they do not have to room to breathe or eat. You should eat small, but frequent, meals and rest as often as you can throughout the day. Your cervix will begin to dilate and efface within the next few weeks to make room for your baby's head to emerge from the birth canal. Your cervix needs to be 10 cm dilated in order to deliver your baby.
