What Happens During Week 3 Of Pregnancy – A miracle has officially happened inside your 3 week pregnant body and biology is celebrating again. When a certain male sperm swims across the ocean and meets a larger female ovum, fertilization occurs, a zygote is formed and begins to reproduce. A blastocyst or ball of cells is formed, which must now travel from the fallopian tube to the uterus. The trip takes about 6 days which includes the 3rd week of pregnancy. When the blastocyst reaches the uterine lining, the blastocyst attaches to the uterine lining, where it will remain for the next nine months.
It is important for parents to understand how and when their baby’s gender is determined. XY and XX: Sex chromosomes occur in pairs like everyone else. A woman only has an XX chromosome (that’s why she is uncomplicated, clear about what she wants and fully organized in life). Males on the other hand have 1 X and 1 Y chromosome (that’s why they can’t ask for directions even if they’re completely gone – ok, so this has nothing to do with being 3 weeks pregnant but it’s true!)
What Happens During Week 3 Of Pregnancy
Fertilized egg: A fertilized egg or zygote contains 46 chromosomes – 23 from the mother and 23 from the father. Now, in the case of sex chromosomes that determine sex, 1 chromosome is received from the mother and 1 from the father. Since the mother only has an XX chromosome, she adds 1 X (so her contribution does not change – as already mentioned, women are deterministic). However, the father has an XY chromosome, so he can add an X or a Y. If the father adds an X, it is linked to the mother’s X, creating an XX child – a daughter. If the father gives Y, it is linked to the mother’s X and creates an XY child – a boy. This means that the gender of the child is determined at the time of conception and cannot be altered or altered by any external factor.

The father determines the sex: It cannot be said enough that the father and not the mother determines the sex of the child. Historically, men have been known to divorce their wives, or take second or third wives because the previous wife was unable to bear a son. It is better to let the mother take a second or third husband if the purpose is to influence the sex of the child.
Once conception occurs, the gender cannot be changed: At three weeks after conception, conception has occurred. Eating small golden balls dipped in ghee, swallowing water that first comes out of the colon, praying to all the gods and everything, visiting astrologers, palmists and numerologists, or the various efforts of mothers-in-law, aunts, neighbors – nothing what can change the gender of the fetus at three weeks of pregnancy. The health of both mother and child can be affected. So, at three weeks pregnant you and your family need to focus on good nutrition and prenatal vitamins for the mother.
Another important change in your uterus: The blastocyst releases the pregnancy hormone hCG which tells your ovaries to stop producing more eggs because fertilization has been achieved. It also activates the increased production of estrogen and progesterone which prevents the lining of the uterus from shedding, thus missing a period. The placenta begins to develop. Amniotic fluid collects around the cells and forms the amniotic sac. The baby now receives nourishment from a primitive exchange between the baby’s cells and the blood vessel cells in the uterine wall. The placenta will take over this task around four weeks of pregnancy.
Note: Although a home pregnancy test at this stage may be positive, a negative result does not mean you are not 3 weeks pregnant. This means you took the test too early and you have to wait another week to check if you are pregnant or not.

Sign up for weekly updates and advice to keep up with your body and baby’s progress during your pregnancy! If last week went well, congratulations, you’re pregnant! In the 3rd week of pregnancy, the single cell (zygote) formed after the sperm fertilizes the ovum has now undergone cell division to become a blastocyst. It is a ball of several hundred cells that is busy growing rapidly. Chances are, you won’t know about your pregnancy at this point if you don’t closely follow the early pregnancy signs.
Should I Get An Early Pregnancy Scan?
After hours of traveling and overcoming obstacles, sperm Mr. Continue in through your egg. Once inside, the sperm’s genetic material meets your egg. Fast! These are single, differentiated cells that carry a unique set of genes and are ready to start your pregnancy.
Your baby begins its journey with this single cell called a zygote. The excited little cell begins to divide itself to multiply exponentially. In 3-4 days, it grows from one cell to two; from two cells to four; four to eight and then to sixteen cells that form a spherical ball called a morula. Over the next 6 days, your little baby ball bounces and rolls through the fallopian tubes on its way to the uterus. In a certain period of time, it grows until a hundred cells gather together to form a blastocyst.
The blastocyst has an outer layer of cells that will develop into the placenta and an inner mass of cells that will develop into your baby. The outer layer of cells begins to produce a pregnancy hormone called human chorionic gonadotropin (hCG). hCG is an important early pregnancy hormone that tells your entire system that you are now pregnant.
When hCG enters your body, the ovaries stop releasing eggs. hCG also signals the empty follicle (corpus luteum) from which your egg is released, to produce increased amounts of progesterone and estrogen. Both hormones continue to nourish and support your uterine wall as nutrients are provided to your baby blastocyst through tiny blood vessels in the wall. This is a form of nutrition for your early developing embryo until the placenta forms in the coming weeks.
Weeks Pregnant: Baby’s Development, Scans And Telling People About Your Pregnancy
Even though all this is happening in your body, you may not have any indication that you are pregnant. Your body is just starting to make changes due to pregnancy and it may take a few more weeks before showing normal pregnancy symptoms.
There’s not much you can do now other than eat healthy and sleep well to support your pregnant body. You may want to check out these early pregnancy symptoms but remember that you may not experience all of them, or worse none of them.
Nasal Congestion (Pregnancy Rhinitis): About 30% of women get pregnancy rhinitis in the early weeks of pregnancy. A sudden increase in pregnancy hormone levels causes the nasal passages to open, increasing mucus production, as a result.
Breast Tenderness: Shortly after giving birth, your body begins to prepare for the coming stages of motherhood, and as a first sign, you may notice that your breasts become tender and sore and may become the dark area around the areolas getting wider and darker.
Early Signs Of Pregnancy
Spotting: Commonly known as spotting, some women may notice light to light discharge, usually brown, in some women around their expected period. It should be noted that not all women experience fear although some may fail to realize it.
Food Avoidance: As pregnancy hormones continue to rise, some pregnant women become sensitive to the taste and smell of food. Don’t be surprised if your favorite Sushi is denied or, oddly enough, you crave chocolate fudge like never before.
Headaches: Headaches are often associated with early pregnancy symptoms. Your body actively produces progesterone, the pregnancy hormone, which nourishes the growing baby with increased blood flow. As a result, the blood supply to your brain can sometimes be reduced, causing you to feel dizzy.
Frequent Urination: When you find that one day you can’t stop going to the toilet from time to time, be happy because nature is warning you with one of the signs that you are pregnant. Human Chorionic Gonadotropin (hCG), an early pregnancy hormone, causes frequent urination in pregnant women.
