9 Weeks Pregnant: Prenatal Check-up is Important


At 9 weeks pregnant, your baby will be completing the embryonic period at the end of the week and the next week, will undergo fetal period. This week, his size is similar to a grape fruit which is 1.67 inches (4.24 centimeters) and weighs a fraction of an ounce. At 9 weeks pregnant, the baby’s appearance is now beginning to change, looking more human now.

Your Baby’s Development this Week

Outside its body

9 weeks pregnant

At this point, 9 weeks pregnant, your baby’s head has straightened, becoming even larger and completely developed with the ears growing, eyes are also formed and eyelids are now in place. However, the eyes will be fused shut until week 26 comes. His main organs have started to develop such as the heart, brain, kidneys, liver and lungs.

Your baby, who will turn into a fetus next week, is also making impulse movements inside your womb. His minuscule muscles are also beginning to form that is why his arms and legs are making those moves. However, you can’t still feel it for at least another month or two. His wrists, ankles, and shoulders, have formed as well as his fingers, and you may be able to see that your baby is starting to thumb suck.

Now, Internal

The nerves are also beginning to work, which makes his small heartbeat. Again, you can’t still feel it right now; however, it is now strong that a fetal Doppler, an ultrasound device, can detect the heartbeat of your little one. But if your doctor can’t find the heartbeat, it does not mean he is dead. Your baby may be in a different position such as back facing out or in the corner of your womb that is why the device can’t actually detect it. The sound will be audible in the coming weeks so be more patient.

The heart has also completed on developing four chambers, the valves are beginning its formation. His tiny earlobes, mouth, nose, and nostrils are also in place. Inside the mouth, his tiny teeth are also forming. Other changes noticeable include his embryonic tail which already disappeared and external organs are also formed; however, doctors won’t still be able to determine the gender. The placenta is now also developed and is now ready to work on producing hormones. It is also making nutrients for your baby and getting rid of his waste products. With these basic physiological changes, his weight will increase rapidly.

Your Body Changes at 9 Weeks Pregnant

Changes outside your body

You are now pregnant, but it’s still not noticeable physically. Week by week, early pregnancy symptoms are becoming a part of your life such as aches and pains, bloating, and fatigue, which most will last throughout your pregnancy (though, the level of each symptoms may vary every week). For this week, you’ll still have frequent trips to the bathroom, around 100 times, to take a leak or vomit and you will also notice that your clothes are becoming tighter especially on your waist area compared to last week. Added to that, you’ll get sleepy all day that you almost don’t want to lift your head from your pillow or even can’t wait to get home, like it’s like you are being magnetized to get in your bed. Extreme pregnancy fatigue is one of the most common symptoms, especially in the first trimester.

Morning sickness continues to linger on you daily, which commonly occurs during pregnancy. Other pregnancy discomforts you may be feeling this week are having heartburns, food aversions, excess saliva, fatigue, frequent urination, breast changes such as tenderness, soreness and swollen. Another hormone that is responsible for your physical symptoms is the relaxin, which is causing pain on your pelvic area, balance difficulties, as well as constipation. However, this hormone is working hard to relax your maternal muscles, ligaments, and joints.

Changes inside

You are experiencing these things because your body is working hard to develop your baby, giving all the benefits he needed for his growth as well as preparing you on the next stage of your life, becoming a mother. Your body is developing placenta, which is your little one’s lifeline. Two more reason is that there is a massive production of hormones in your system and your metabolism is increasing, causing your blood sugar and blood pressure to reduce.

Your uterus has grown this week, and it is now similar to a size of a cantaloupe when you are 9 weeks pregnant. You may be also feeling more bloated and maybe a bit sluggish. Your weight gain will also increase; however, it is more likely due to water retention than the baby. Most women said they have severe mood swings as well as other known pregnancy symptoms during their 9th week of pregnancy. It is because of the progesterone and estrogen hormones making changes in your body and it will continue to do so until childbirth.

What to Think and Do this Week

Sure that you have already many complains right now as you struggle being a pregnant woman. However, as you are expecting your little one to come out, you should do the necessary things for both of you. Now that your baby is transitioning to fetal period and that more developments will come to your baby, you should now see a genetic counselor. Talk to them about your history of genetic disease or illness in your family (if you have one). They will help to refer you for a prenatal test including chorionic villus sampling or CVS. The said test is generally done when you are between 9 to 12 weeks pregnant.

In order not to have birth defects and pregnancy complications, eating the healthy foods and healthy lifestyle is a must. You should also now be taking prenatal vitamins such as folic acid supplements, which is important for the development of your baby. If it is your first time being pregnant and you are struggling with the pregnancy symptoms, ask some advice from your friends or participate on support groups. This will help you to cope the things your experiencing right now as well as more understand these changes during your pregnancy. While you are having these pregnancy discomforts when you are 9 weeks pregnant, you will find more relief if you have active lifestyle and social communication.
