Pregnancy Week 3 – Weekly Development

The third week of your pregnancy is here and for some exciting news, your barb’s development officially “flags off” this week. Now, although you have been medically pregnant for two weeks, and you wouldn’t confirm that you’re officially pregnant until week 4 or week 5, but inside of you, a new organism is beginning to form. 

In week two, fertilization took place. The sperm and the egg came in contact with each other and following the natural process, they made your future baby. However, as with weeks 1 and 2, you may not even be aware that you’re pregnant. Conception typically took place at the end of the second week of your pregnancy and week 3 is too early for you to have missed your period. 

With the perfect timing that you practiced in week two, the blastocyst formed after fertilization is most likely on its way to your uterus. You would feel any of this on the outside anyways. 

After the follicle releases the egg, the now empty space would be taken over by a yellow group of cells known as the corpus luteum. This group of cells is responsible for producing sufficient pregnancy hormones like estrogen and progesterone — enough to last your future baby up to 10 weeks until the placenta takes over nourishment. 

If you test during the third week, you would most likely not get a positive pregnancy test result. 

Right now, your future baby is around the size of a pinhead. 

Your Baby’s Development 

Implantation may occur during the third week of pregnancy. Implantation basically refers to the process by which the blastocyst attaches itself to the uterine line. Under normal circumstances, it takes about 8-9 days for this process to be completed after fertilization, however, it may occur as early as 6 days in some women. 

But let’s not get ahead of ourselves. Right after fertilization, what the sperm and egg merge to form is now referred to as a zygote. The cell contains a whole lot of information and a lot of activities are going on in there. 

Your chromosomes and your partners’ are combined to determine the gender of your future baby, hair color, eye color, and even personality. 

This zygote travels down to the uterus and as it travels the cells divide and one cell becomes two, then two become four and then eight. These cells are responsible for multiplying and forming every organ in your future baby’s body. 

And at this point, the cells are a solid ball. It is when the ball of cells gets to your uterus and hollows out to form a blastocyst which then attaches itself to your uterine lining that you become actually pregnant. 

Some other interesting events take place during pregnancy in week 3. It is very possible for a single future baby to become two. Identical twins are formed with the same egg and sperm with identical genetic material.

 The egg which is already fertilized can be divided into two groups of the same identical cells at different stages including the two-cell stage or the blastocyst stage. Usually, this takes place during the first week post-conception. 

Another likely occurrence which is of course, mutually exclusive to identical twins is fraternal twins. Unlike identical twins, fraternal twins come from different eggs and are fertilized by different sperm cells. Fraternal twins typically require two sperm cells and two eggs for them to be formed. 

Your Symptoms 

Many changes are going on in your body but you cannot feel them physically. During week 3, there is no credible way to confirm that you are pregnant and the physical symptoms wouldn’t begin to exhibit themselves yet. 

Week 3 is still considered a part of the early days in your pregnancy and just like weeks 1 and 2, you may not feel very different. 

At week 3, there is a strong possibility that you haven’t missed your period yet and therefore cannot begin to suspect anything. And even if you have been deliberately trying to conceive, there is no clear physical evidence. 

Most of the early symptoms of pregnancy are caused by pregnancy hormones, and at 3 weeks, they would still be at a pretty low level in your body. 

However, this doesn’t imply that they are completely absent. Therefore, here are some symptoms that you may notice during the third week of your pregnancy: 

1. Unstable Emotions 

Pregnancy brings with it hormones that make you feel a tad more emotional than you would normally do. You might feel excited at a point given that you have started the journey to bring new life into the world. At other times, you may feel very anxious or nervous while waiting to be able to take a pregnancy test. 

You would almost feel these emotions on a different level and they can be pretty difficult to keep under wraps. You need to understand that it isn’t out of place at all. Pregnancy can open you up to a barrage of emotions regardless of how early. 

2. Spotting

Upon reaching your uterus, your future baby implants itself or in other words, find a spot on the uterine wall to attach to. While burrowing in, there is the possibility of a bit of spotting or bleeding happening. 

If you don’t experience spotting, it doesn’t, of course, mean that you’re not pregnant, you probably just didn’t experience it. It doesn’t occur in all women. 

3. Nausea

At three weeks, this would be a pretty rare occurrence but it cannot be counted out. The pregnancy hormone hCG or human chorionic gonadotropin would start to move through your body and may result in feelings of nausea or queasiness and sometimes, you may feel a strong urge to puke. 

However, if this symptom is evident in you at three weeks, then you’re probably further along than you calculated. Also, the alternative reason is that you may be three weeks pregnant, but with twins. 

Women carrying twins typically have more pregnancy hormones and would, therefore, experience worse nausea and maybe even earlier than usual. 

4. Breast Changes

You may start to feel your breast getting sore with the nipples darkening. This is all in preparation of your body starting to make milk. 

5. Missed period

There is a possibility of confirming your pregnancy towards the end of the third week if your cycle isn’t up to 28 days. The real confirmation would happen when you take a pregnancy test of course. 

6. Frequent Urination 

You may feel the urge to urinate a little more frequently than you used to. It would almost feel like your bladder is filling up twice as fast. This is an early symptom and one that you should look out for too. 

Measures To Observe 

As always, there are measures to observe for pregnancy week 3 just like every other week. Most of these measures are those that you already started and would just be emphasized on, as well as a few new ones, here goes:

1. Consume More Iron and Vitamin C 

Your body is going to experience an increased volume of blood and vital nutrients like iron need to be topped up. To boost your body’s iron absorption rate, vitamin C to the rescue. 

So, you would need to consume lots of fruits and vegetables, since that is where vitamin C lives. For Iron, take in a lot of beef, soy product, dried fruit, and of course, poultry. 

2. Take More Calcium Too!

Calcium is essential for the proper growth of your future baby. It is the major player in the growth of strong and healthy bones as well as muscle health, nerve, and heart. If the calcium level in your body is insufficient, your baby taps into those in your bones. 

A great source of calcium is Greek or frozen yogurt, you could take up to three or four servings daily, and this would be around 1000 milligrams. You could also consume lots of hard or pasteurized cheese and calcium-fortified cereal or juice.

3. No To Hair Coloring 

Now, this might seem like a strange mention, but you actually need to take this very seriously. Experts are of the opinion that regarding hair coloring, it would be foolish to take any risks. 

So, if you intend to retouch those roots, at least wait until the end of the first trimester. Also, you should probably pause on using single-process color, go with highlights so that the chemicals do not come in contact with your scalp.

 Request for less-harsh processing such as an ammonia-free base. The reason for all of these is that hormones could make your hair react differently. Even using your regular stuff, you might still get a different reaction.  

Suggestions 

Observe all the measures that you started in week 1 or week 2, and if you haven’t started, you’re already in the know enough to know better. 

And if you haven’t gotten a positive result yet, don’t stress (recall it was mentioned in the previous week). Instead, you should be resting a lot and trying to ensure that your physical and mental health remains in prime state.
