Fetal health and development

You are pregnant. Congratulations! Are you curious about the development of your baby, about Fetal Health and Development, and how to take care of it?

Do not worry. We have got a complete guide for you that will help you in every step of your pregnancy.

A normal pregnancy lasts for nine months and each three-month period of your pregnancy is termed as a trimester.

During this trimester, the fetus grows and develops. Make sure that you see your health care provider a number of times to ensure that your pregnancy is going well.

Your first visit to the doctor is usually before 12 weeks; however, they will schedule appointments during the weeks 16, 24 to 28,32,36,38, and then finally weekly.

Doctors usually think of pregnancy in 3 stages called trimesters. These are:

  • First trimester: Conception to week 12
  • Second trimester: Weeks 13 to 28
  • Third trimester: Weeks 29 to birth.

Fetal health and development are an important part of your pregnancy. To understand fatal development, let us discuss the changes it goes through in each trimester.

Fatal Development

During your early visits to the doctor, you may hear them using various terms like embryo, zygote, and fetus.  These terms describe the stages of your baby’s Fetal Health and Development.

Here’s more about what the terms mean and what you can expect along the way.

What is a Zygote?

Fertilization is a process that usually happens within a few hours of ovulation. It is a critical point of reproduction as in this process; the sperm meets the newly released egg.

At this point, 23 male chromosomes and 23 female chromosomes mix to create a single-cell embryo called a Zygote.

Embryo and Fetus

A baby to be is not considered a fetus until the 9 weeks after conception or week 11 after your last menstrual period. (LMP)

The embryonic period consists of the development of all important systems of the baby. You can think of it as your baby’s basic foundation and framework.

On the other hand, the fatal period is more about growth and development so that your baby can survive in the world. you can visit our page for Gynecology Services here.

Let us discuss the stages of Fetal growth and development month by month.

Stages of developmentFirst trimester

The span of this trimester is from the week of conception to 12 weeks. This is generally the first three weeks of your pregnancy.

Your baby will undergo small changes; form a small group of cells to a fetus that is starting to have baby’s features during this stage according to American College of Obstetricians and Gynecologists

Month 1(week 1-4): A water-tight sack forms around the fertilized egg and is called an amniotic sac. It helps cushion the growing embryo.

The placenta also develops during this stage which is a flat organ that transplants nutrients from the mother to the baby and transfers waste from the baby.

Think of the placenta as a food source for your baby.

During this stage, a primitive face will take form with large dark circles for the eyes, and the face will start developing.

Blood cells will take shape and circulation will begin. The tiny heart tube will start beating 65 times a minute by the end of the fourth week.

Your baby is about ¼ inch long by the end of this month which is smaller than a grain of rice.

Month 2(week 5 to 8): The facial features of your baby will continue to develop. Tiny buds eventually grow into arms and legs, fingers, toes, and eyes are formed.

The neural tube i.e. the brain, spinal cord, and other nerve tissue will form. The sensory and digestive tract will form and bones will start replacing cartilage.

The head of your baby is the largest in proportion to the rest of its body at this point. The heartbeat can be detected at about 6 weeks.

Your baby is about 1 inch long and weighs about 1/30 of an ounce.

Month 3(week 9 to 12): The arms, hands, fingers, legs, feet, and toes fully develop. External ears form and your baby will start moving a little.

The teeth and gums will form and the reproductive organs of your baby will also form but at this point, it is difficult to distinguish your baby’s gender on ultrasound.

The circulatory system and the urinary system of your baby are working.

Your baby is 4 inches long and weighs about 1 ounce by the end of this month.
