How Big is the Baby at Nine Weeks Pregnant?
By pregnancy week 9, your baby is between 22 and 30 mm long, (that's about an inch) or about the size of a large grape. Your baby weighs less than one ounce at, but will soon start putting on weight dramatically as you continue your pregnancy week by week.
Your Baby's Growth and Development
How your baby's growing:
Your new resident is nearly an inch long — about the size of a grape — and weighs just a fraction of an ounce. She's starting to look more and more human. Her essential body parts are accounted for, though they'll go through plenty of fine-tuning in the coming months. Other changes abound: Your baby's heart finishes dividing into four chambers, and the valves start to form — as do her tiny teeth. The embryonic "tail" is completely gone. Your baby's organs, muscles, and nerves are kicking into gear. The external sex organs are there but won't be distinguishable as male or female for another few weeks. Her eyes are fully formed, but her eyelids are fused shut and won't open until 27 weeks. She has tiny earlobes, and her mouth, nose, and nostrils are more distinct. The placenta is developed enough now to take over most of the critical job of producing hormones. Now that your baby's basic physiology is in place, she's poised for rapid weight gain.
Your baby is growing like crazy during pregnancy week 9. By now, most of the aspects of your baby's physical structure, such as head, arms, legs, and torso are in place. If you were to peek in on your little one, you'd find they resemble a miniature human being (one with a very large head!). Because your baby's organs and limbs are forming, in the next few weeks, your baby will be putting on weight. Your baby's tail should have disappeared by now, and your baby's organs and muscles should be functioning on their own. It's hard to believe that something so small can function so completely, isn't it!
At 9 weeks pregnant, your baby's eyelids will fuse shut and won't open up again until your baby is about 27 weeks along. Your baby's face is becoming more distinct every day, with the mouth, nose and nostrils becoming clearly visible. By nine weeks, your little one will even have developed sex organs, however, your healthcare provider won't be able to discern them quite yet. Typically the sex of your baby can be determined by ultrasound between 18 and 20 weeks gestation.
Your baby's heart should have divided into four separate chambers now, as your baby swims about gleefully in his or her warm and cozy home.
Your Growth and Development
Your uterus is still growing, now closer to a small cantaloupe than a grapefruit. By this week, you may notice that you feel more bloated and lethargic than ever before. You may notice an increase in weight gain, which may be more associated with fluid retention than actual weight. This may apply throughout your pregnancy week by week. One thing you should avoid doing while pregnant is weighing yourself every day. Weight gain can fluctuate as much as 1-5 pounds in the course of a single day, and such fluctuations can be discouraging. If you can hold off until your prenatal visits, you might avoid the pain of constant weight fluctuations. If, however, you are determined to weigh yourself frequently during pregnancy, consider weighing once a week, at the same time of day, right after you get up in the morning and empty your bladder. Doing so will provide the most consistent results and will help eliminate excessive worries about daily weight changes. A new pair of maternity jeans will relieve the anxiety related to weight fluctuations.
Not all the weight you gain is stored as fat. At birth, your baby may weigh between 6 to 8 pounds. The uterus expands during pregnancy and may weigh about 2 pounds. The afterbirth or placenta generally weighs 1.5 pounds. Your breast tissue will grow during pregnancy and may weigh up to 1.5 to 2 pounds. Your blood volume will increase and add up to 4 pounds of weight. The fluid retained by your body during pregnancy can weigh as much as 4 pounds. The amniotic fluid surrounding your baby will weigh approximately 2 pounds. The maternal fat stores will add about 7 pounds of weight to your total weight gain. By the end of pregnancy you will gain approximately 18 to 35 pounds.
Here's the skinny on losing pregnancy weight after you deliver your baby... most women will lose the bulk of their pregnancy weight in the first three months after delivery. In general, you will lose 10-13 pounds during the birthing process from the weight of the infant and placenta. An additional 7-11 pounds will be lost after the first postpartum week. The remaining extra pounds will be shed with good eating habits and a regular exercise program. You will be back to your normal weight and fitting into your pre-pregnancy clothes in just a short few months, as long as you take care to exercise and eat healthily in the weeks following pregnancy.
Changes in You
How your life's changing:
You still may not look pregnant even if your waist is thickening a bit. You probably feel pregnant, though. Not only are morning sickness and other physical symptoms out in full force for most women, but you may feel like an emotional pinball as well.
Mood swings are common now — it's perfectly normal to feel alternately elated and terrified about becoming a parent. Try to cut yourself some slack. Most women find that moodiness flares up at around six to ten weeks, eases up in the second trimester, and then reappears as pregnancy winds to a close.
Many women start experiencing pregnancy related mood swings and anxiety during their pregnancy at 9 weeks. You may alternate feelings of elation with feelings of trepidation. Many pregnant women find themselves crying over small things like commercials. Remember that these emotions are perfectly normal, and largely the result of the increased number of hormones floating through your system. Higher than normal levels of progesterone in your pregnancy body can also lead to more fatigue, which can influence your moods.
If this isn't your first pregnancy, by 9 weeks pregnant you may have noticed that your belly has 'popped' just a bit. This is an exciting time, though many women look forward to the months where they are actually showing and not simply looking a little rounder than usual.
Some unpleasant pregnancy symptoms that might pop up during this pregnancy at 9 weeks are bloating and gassiness. Many women find they are more prone to flatulence and burping, as well as highly abnormal guttural sounds during pregnancy. Relax, and know that these too are normal and simply the result of increasing hormone levels, particularly progesterone in your body.
A Dream Enhancement Tool during Pregnancy
Pregnant women are more likely to experience unusual dreams during pregnancy. This often results from increasing levels of hormones rushing through your body, combined with many emotions surrounding the pending delivery of your newborn baby. Some women find their dreams very interesting while others find they interfere somewhat with their ability to feel rested after sleeping.
