Conceiving Your Bundle of Joy at 3 Weeks Pregnant

Overview

At 3 weeks pregnant, your ovulation occurs and this is the miraculous moment that happens inside your body. You are now called a pregnant mother. At this point, you now have conceived your little bundle of joy as you are confirmed 3 weeks pregnant!

Your egg and your partner’s sperm have successfully united and at the time of conception, a ball comprised of cells is formed, and is now called blastocyst. The single sperm was able to go through the strong outer covering of your egg and then fertilized it. Your soon-to-be baby will now begin to travel to your uterus from your fallopian tube in 6 days. As soon as it reaches your uterus, the fertilized egg will hold on onto the lining of your uterus or also known as your womb. At 9 months pregnancy, you will be welcoming your baby.

Your Baby’s Growth while You're 3 Weeks Pregnant

The crucial meeting of your egg and your partner’s single sperm will take 24 hours. The fastest single sperm will enter the egg’s center. Your egg will then block other sperm to enter by building a protection around. After this process, the egg will be fertilized and now will be called zygote. The zygote will then divide rapidly, becoming 12. 

At this point, the zygote is staying in the fallopian tube and is looking for a way to travel down your uterus. The cilia, which is present in your fallopian tube, keeps the zygote from going to another settling point in your body. The fertilization of the zygote will take 60 hours.

After it is fertilized for about a week in the fallopian tube, it will then attach itself in the uterus lining. This time, it is called blastocyst. The small blastocyst cell or your future baby, which consists of 100 cells, just a few days following the first meeting between sperm and egg have made its way to your uterus. The fertilized egg has 46 chromosomes, with 23 from you and 23 from your partner. It has also broken down into several parts rapidly, and one of its parts will soon become the placenta. This week also, though you still don’t know the gender until the coming birth month, it has already been determined.

You, the mother, will always give an X chromosome while your partner may provide either a Y or an X. In case the sperm that was able to fertilize your egg carries an X chromosome, then the resulting XX zygote will be a girl. On the other hand, in case the sperm is Y-bearing, then the XY zygote will be a boy.

Happenings on Your Body this Week

Inside your womb

On this week, your small blastocyst is taking nutrients and oxygen as well as dumping waste through a primeval circulation system. It consists of tiny tunnels that link your baby to the blood vessels in the uterine wall. On the other hand, the placenta is not fully developed enough to function until the end of next week. Your baby is on the same size of a pin head.

The part of the blastocyst cell in which the placenta will be formed has now begun to create HCG or human chorionic gonadotropin, a pregnancy hormone which will prevent your ovaries from releasing eggs. It will also produce more estrogen and progesterone. The said hormones result to changes in your body as well as causing symptoms like morning sickness and nausea. These will also stop your uterus from shedding its lining and stimulate the production of the placenta.

While the placenta is still unable to do its work, nourishing and maintaining the fetus, the production of progesterone hormone will continue for about 7 weeks until the placenta can finally do its job. This hormone mostly affects your body and the brought out most early pregnancy symptoms.

On your body

One is the tingling feeling on your breast and causing your nipples’ tenderness, causing additional fats on your body, nausea, and digestive problems such as constipation, indigestion and reflux. However, it also helps your baby to have food from deposits of glycogen and giving you smooth muscle which reduces the possibilities of having premature birth.

Meanwhile, the amniotic fluid has started to gather around the small cells, which will soon become the amniotic sac. This will serve as the cushion of your baby inside your womb. At this week, your body’s immune system is also subdued which is the reason why your baby is not rejected as a foreign object inside your body.

Other changes in you includes being sensitive to a certain smell which often triggers nauseous feeling, strange taste in the mouth, feeling odd, frequent urination, picky on foods or even averting to eat and having high basal body temperature.

What to Do at 3 Weeks Pregnant

When you already know that you are pregnant and have conceived, you should now be aware of the risk around you that will affect the early development stage of your baby. If you are going for a checkup for other medical reasons, inform your health care provider about your pregnancy. Taking X-ray examination is not recommended while you are on the initial stages of pregnancy.

Avoid using or going to places that uses or with pesticides and poisons such as farming area. These things greatly affect the cell division of your developing child. Now that you have conceived, start changing your bad habits including drinking alcohol or taking unnecessary medications. Make sure you consulted your health care providers regarding what medications to take. They may suggest you to take prenatal vitamins that contain folic acid supplement as well as calcium.

If you are not a fan of vegetables, this time of pregnancy, it is important to eat green leafy foods as well as nutrient rich fruits. Eat food that are also rich in iron that is good to increase your blood and foods with vitamin C like oranges.

Do some exercises. But before you go for that, always consult your doctor. When exercising, concentrate on keeping your heart healthy by doing cardiovascular exercise.
