How your baby's growing:
Your baby is really starting to fill up your uterus. This week he weighs almost 2 pounds and is about 14.4 inches long with his legs extended. He can now open and close his eyes, and he sleeps and wakes at regular intervals. He may suck his fingers, and although his lungs are still immature, they would be capable of functioning — with assistance — if he were to be born prematurely. Chalk up any rhythmic movement you may be feeling to a case of baby hiccups, which may be common from now on. Each episode usually lasts only a few moments, and isn't bothersome to him, so enjoy the tickle. With more brain tissue developing, your baby's brain is very active now. Wonder what he's thinking?
This week marks the beginning of the third trimester — and a big developmental change as Baby's fused eyelids finally open. The lids have been closed since early pregnancy to protect the developing retina at the back of the eye. The retina is the part of the eye that receives light information, and transmits the information to the brain for interpretation. The retina develops its normal layers during this week.
*Although Baby may not have grown much taller, she now weighs more than two pounds. Right now, your baby looks like she will at birth, just a little thinner and smaller.
*Other developmental changes include:
Lungs, liver and immune system are still developing.
*As hearing continues to develop, some scientists suggest Baby may start to recognize your voice, although sounds may be muffled because waxy coating still covers the ears.
*Response to sound will become more pronounced as the development of the auditory nerve is completed.
*Baby's brain continues to grow and develop rapidly.
Your frisky fetus is on another growth spurt, shooting up half an inch this week to measure about 14 inches from head to toe. She weighs roughly 2 1/2 pounds, and will gain approximately half a pound each week for the next 10 weeks. The average full-term baby weighs about 7 1/2 pounds and measures from 18 to 20 1/2 inches, but many normal, healthy babies fall outside this range. Unless your practitioner has told you of a potential problem, it's safe to assume that your little one is right on track.
How your life's changing:Your body is gearing up for the final lap, so you may start noticing some new symptoms. Along with an aching back, for example, you may find that your
leg muscles cramp up now and then. They're carrying extra weight, after all, and your uterus is putting extra demands on your circulation. (As your uterus expands, it puts pressure on the blood vessels that return blood from your legs to your heart and on the nerves leading from your trunk to your legs.) Unfortunately, the cramps are likely to get worse as your pregnancy progresses. Leg cramps are more common at night but can also happen during the day. Flexing your foot (by pointing your toes forward and then flexing them back toward your shins) stretches the calf and should give you some relief. Walking for a few minutes or massaging your calf sometimes helps, too.It may be the furthest thing from your mind right now, but it's not too soon to think about
family planning. You'll want to have made some decisions before your baby arrives. And in some states, if you're considering a tubal ligation during your hospital stay, laws require that you sign a consent form at least a month before delivery day. (You can still change your mind later.)
As your uterus has grown and you've gained more weight, your ligaments are also getting looser in preparation for delivery, which can make your hips feel unstable or loose. This loosening and shifting may cause occasional sharp pains in your pelvic area that can get stronger with each successive pregnancy. It's important to move slowly and deliberately, and avoid sudden movements.
You may notice that it's getting increasingly hard to breathe as the uterus continues to expand near the rib cage, adding more pressure to your lungs. Getting a bit breathless is expected; you and your baby are still getting all the oxygen you need.
Also around this week, you may begin noticing some changes in your behavior, due to hormonal changes and everything that’s on your mind. For example, you may have trouble concentrating, keeping track of belongings, or remembering important things. You can help yourself to feel more in control by trying to minimize the stress in your life, getting plenty of rest, and taking those brief memory lapses in stride.
Speaking of weight gain, you're probably up 15 to 20 pounds by now, with your uterus banging against the bottom of your rib cage. So--feeling sexy? Many women continue to enjoy sex up until the last few weeks (or days) of pregnancy, but don't be surprised if, at this point, your interest in french fries far exceeds your appetite for your partner's caresses. Alternately, some women find that they feel especially sensual as they grow more voluptuous, while their partners have suddenly lost interest--the "Yikes, I'm having sex with a mom" syndrome.
