Your BabyYour baby is getting plump. The fat deposits are now beginning to offer form and fullness to your baby's legs and arms. Your baby is taking up most of the room in your uterus, so there is a lot less room to move around. Also, your baby's lungs are now completely developed and producing what is called surfactant, a substance that helps in the exchange of oxygen in the lungs. Your baby is now approximately 18 inches long and weighs about five pounds. If you were to have your premature baby now, you'd be happy to know that there is a 99 percent chance of the baby surviving.
Your BodyYour routine visits to your healthcare provider may start to include the checking of your cervix now. Your doctor is checking your cervix for signs of effacement and dilation, the indication that labor is not far off. You may be having trouble sleeping now and there are also numerous physical reasons that sleep may be difficult. For instance, the baby may be putting extra pressure on your bladder and going the bathroom every 45 minutes isn't conducive to sleep. You may also have a backache, swollen feet or may not be able to find a comfortable position. You may want to try doing pelvic tilts before bed, limiting fluids after a certain time, and being tired when you go to bed can also help you in falling asleep.
