your symptoms and changes during the 9th week of pregnancy.

Your Baby

During pregnancy week 9 your baby will grow up to 30 mm in length or will grow to roughly 1 inch long! Your baby now weighs less than one ounce but will start rapidly gaining weight as you continue your pregnancy.

Changes in Your Growing Baby

Your baby is working diligently to grow organs and limbs. Your baby now has all it's primary physical features in place including her arms, legs, torso and head. By now your baby's organs and muscles are communicating with one another and starting to move independently. Isn't it amazing to think how someone so small can move so uniquely?
The babies eyelids are fused and remain closed until roughly 27 weeks in your pregnancy. Your tiny baby will have his or her sex organs developed now, however most healthcare providers aren't able to tell the difference between a boy or girl baby until roughly 17 - 20 weeks of pregnancy. The heart will have separated into four unique chambers by now. Your baby is spending most of his or her time swimming about in the warm and inviting amnitotic fluid.

Your Body's Development

Your uterus is closer in size to a small melon than a large grapefruit. You might start to feel even more tired and bloated than you have in weeks past. Some women start retaining fluid which may contribute to weight gain now. Of course, many women continue to retain fluid as they continue their pregnancy. The good news is this weight comes off very quickly after you give birth.
Keep in mind that any water you are retaining does impact your weight gain. You should limit your weigh in sessions to once per day (or better once per week) as your weight may rise or fall up to 5 pounds in one day (solely based on water retention). Some women find these fluctuations very stressful, thus it is better not to dwell on them if possible.
You may start wondering where all the weight will go that you gain during pregnancy (after all, your baby will only weigh between six and eight pounds in most cases!). Pregnancy weight is distributed throughout your body. A woman's uterus for example generally grows to weight 1 pound during pregnancy. Some women will gain 1 to 3 pounds of breast tissue. Your blood volume also increases dramatically adding as many as four pounds to your total weight gain. Even the amniotic fluid causes up to 2 pounds in weight gain. Most women will also put on roughly 7 pounds of body fat during pregnancy. Remember each pound of fat goes toward nourishing and providing the best environment for your child to thrive in. While you don't want to gain 80 pounds if you can avoid it, this is the one time in your life you should not obsess about weight gain. Keep in mind with a sensible diet and routine exercise, you'll be back into your fit and trim shape a few months after delivery.

Changes in Your Body

By 9 weeks pregnant you have probably noticed some mood swings or anxiety. Many women alternate between feeling elated and feeling anxious or down. This is perfectly normal, as is crying frequently during pregnancy. Many women find the experience quite cathartic. Remember that pregnancy does a number on your hormones, which is largely the reason you are feeling up then down in the course of a day. Try to relax when possible and keep a positive outlook. Go for a walk and get some fresh air to lift your spirits when down, and remember in the end you'll be blessed with a beautiful new baby.

Fatigue during Pregnancy

Are you feeling more exhausted than normal? Fatigue early in pregnancy is expected. In the first trimester, your body is working harder than ever to support your developing baby. In addition, hormonal changes, especially the increase in the hormone progesterone, can contribute to you feeling absolutely worn down.
If you are suffering from morning sickness, you are probably feeling pretty tired. All that nausea and vomiting can zap up your energy. You may also have fatigue if you're worried about your pregnancy, since stress and anxiety can be quite draining.

Fatigue is a common pregnancy symptom in the first 13 weeks of pregnancy, but it will diminish and go away in the second trimester. You will slowly start to feel like your old self in a few weeks. The middle trimester is often referred to as the "honeymoon" of pregnancy, since many of your early pregnancy symptoms will go away. Enjoy your renewed energy levels in the second trimester. Until then, try to take it easy and try to rest as much as you can.
