At 9 weeks pregnant, you are in the first trimester of pregnancy and the fetus is only the size of a grape. At this time, the fetus has started to have all parts and is increasingly taking the shape of a baby.

1. The development of the 9th week fetus

At this stage, the fetus is nearly 2.3cm long, weighs about 20g and will gain weight quickly. The baby's head is still larger than the body, but will become more proportional in the weeks to come.
During the 9th week, the fetal tail disappeared and was replaced by two legs and toes appeared. All four chambers of the heart have been formed and other organs are being developed. Some small muscles in the legs and arms have been formed, so the baby will have spontaneous movements. Small baby teeth and jawbones are also forming. Over the next week, the teeth will harden and connect to the jawbone.

If you have an ultrasound at 9 weeks, your doctor will not be able to determine the sex of your baby, but you will be able to see some very small movements of the baby. At this stage, you can also hear your baby's heartbeat if you do a Doppler ultrasound. Don't worry if you can't hear the heartbeat at this time, your baby may be turning away and "hiding".

2. Changes in pregnant women in the 9th week of pregnancy

Fatigue: At this week of pregnancy, you will still feel tired. Your body is working hard to form the placenta to provide nutrition to the baby and this will take a lot of effort. Furthermore, the metabolic rate and hormone levels are increasing, leading to a drop in blood pressure and blood sugar, causing severe fatigue. This feeling of fatigue will subside as the placenta is fully formed.

Frequent urination: You may have to urinate many times a day and this is a common phenomenon. The hormone hCG increases blood flow to the kidneys and increases the kidney's ability to filter waste, so you'll feel like you have to pee more. The growing fetus and pressure on the bladder can also reduce the ability to hold urine.
Pain and discomfort in the breasts: During pregnancy, your breasts will gradually enlarge and create pain or discomfort as your body is preparing to make milk for the baby. The pain will subside after the first pregnancy and your breasts will return to normal after delivery.
In addition, bloating and constipation will continue as in the previous week of pregnancy. Please continue to rest, eat right, sleep more to ensure health. The first 3 months are the most sensitive time during pregnancy. In order for mother and baby to be healthy, parents need to pay attention to:
Understand early signs of pregnancy, pregnancy poisoning, bleeding during pregnancy. Timely, correct and sufficient first prenatal check-up, avoiding too early/too late. Fetal malformation screening at 12 weeks detects dangerous fetal malformations that can be intervened early. Distinguish between normal vaginal bleeding and pathological vaginal bleeding for timely intervention to maintain pregnancy. Screening for thyroid disease in the first 3 months of pregnancy avoids dangerous risks before and during delivery.
