4 Week Pregnancy

4 Week Pregnancy

Most women would still expect their period to arrive. If it does not occur, congrats – you might be pregnant. Every woman is unique, so your feelings and general state can follow its own path. Although, there are some symptoms that are quite common for a greater part of pregnant women during this gestational stage. 

 

 

What happens and What to expect in the fourth week of pregnancy?

Physiology

While most of pregnant women are oblivious about the miracles inside their womb, a little baby is getting very busy. By this moment, the fertilized egg has already come to the uterus, and great changes are going to happen. This little cluster of cells will soon divides into two parts. The first part is going to form an embryo of your child, and the second is going to turn in a placenta.

 

The size of an embryo can be compared to a small freckle on your cheek. It is surrounded by the amniotic sac that protects it together with placenta delivering nutrients necessary for the development of your baby and excreting wastes. 

Embryos consist of three thin layers each forming specialized organs and parts of baby’s body:

Endoderm will turn into the digestive system together with lungs and liver. 

Mesoderm is responsible for forming sex organs, bones and muscles, heart and kidneys.

Ectoderm comprises the nervous system, eyes, hair and skin. 

 

Although the placenta consists of a shared tissue with your baby, your and your baby’s blood systems don’t come into a direct contact.

Expectations and feelings

Some expectant moms swear they feel the egg hunker into the uterus wall and get cozy there. It could be a twinge similar to normal ovulation. If you are in tune with your body, you could notice subtle changes of your general state that can be associated with pregnancy. However, you should remember, that our mind could play tricks on most of us, so to confirm your new state you need to make a pregnancy test. 

 

It is important to wait until the expected date of your period – you see, over-the-counter tests detect the levels of HCG produced after the implantation. If a woman takes the pregnancy test too early, there can be a negative outcome even if there was a conception indeed, as the levels of HCG in your body are still too low.

 

False hopes are the other side of taking pregnancy tests too early. In some cases women can experience a miscarriage because the fertilized egg couldn’t embed into the uterine lining properly. You may get a positive result, but in a week or too you will get your period.

 

Some women might start realizing slight changes; feel a bit tired and clumsy. 

 

 

Pregnancy symptoms before implantation

Implantation starts between 6 and 12 days after conception. Is it possible to feel any changes in your body before the implantation?

 

Many women tell that they felt they were pregnant very early, even before taking a pregnancy test. 

 

You have to be strongly in tune with your body to feel the slight changes caused by the fluctuating hormones before implantation. Usually the first pregnancy symptoms appear only during the fourth week. 

 

It takes about one day for a sperm to fertilize your egg which starts its journey through the fallopian tube. This short travel lasts for 4 days before entering the uterus. Implantation occurs normally in 8-9 days after ovulation.

 

Although the levels HCG raise soon after conception, they are still too low to provide noticeable changes, so most women don’t feel anything special.

 

4 week of pregnancy early signs and symptoms

A healthy start on the pregnancy is a great way to ensure a smooth period of nine months ahead. Although a pregnancy test is one of the best ways to confirm your new state, there are some earlier signs that can show you should take one.

 

You might also take these early signs for your period being about to arrive.

First signs

•Spotting and changes in menstruation are the most obvious signs of pregnancy. Some women can have spotting or slight bleeding in about 10 days after conception, and the reason is that the embryo is implanting into the uterine wall. After the implantation bleeding your periods normally stop altogether. However, in rare cases pregnant women can experience irregular bleedings.

•Bloating is a sign of pregnancy, too. As the lining of your uterus begins to thicken due to the rise of hormones, you can feel more bloated than usually before ovulation.

•The similar symptom of an embryo implantation is backache.

•Breasts become very tender and fuller than usual. The areolas become darker due to the hormone imbalance. Sometimes prickling nipples are noticeable within a week or two after conception. Your body changes in order to support a new life inside, and when it gets used to the rise of hormones this symptom subsides. 

•Another telltale symptom of pregnancy is morning sickness. It can last between 4 and 8 weeks after implantation. The reason of nausea is the high level of hormones causing food to empty the stomach too slowly. Pregnant women are very sensitive to certain smells and odors triggering nausea. The sense of smell becomes so sharp, that some bad odors can even cause vomiting. You are not alone if you suffer from morning sickness. 50 to 90% of future moms have some degree of nausea during the fourth week of their pregnancy, and this feeling normally ends with the start of the second semester.

•You could be successfully conceived if you feel sleepy even in the morning. Changes in hormone levels may cause fatigue. 

•Fluctuating hormones also can evoke strange food cravings and aversions to unusual beverages. 

 

There are also many other pregnancy symptoms like frequent urination, but most of them take place only after 6-7 weeks pregnant. Every case is one and only, so you may not experience the symptoms mentioned above. If you feel dizzy and uncomfortable, try not to stress about your state, as these symptoms will subside very soon.

Fetus in pregnancy size 4 week

Fetal development is quite fast during this stage. The ball of cells becomes an embryo of smaller than 3 mm, and it’s growing inside the womb. Its size can be compared to a poppy seed.

 

All the three layers of the embryo develop rapidly to form basic organs and systems of the baby. The yolk sac makes red blood cells and carries nutrients for the growth of your baby. At the same time, an early version of umbilical cord and placenta start functioning and burrowing into the uterus wall creating micro net of chorionic villi.

 

By the end of the fourth week the placenta will work correctly becoming able to carry food for the baby and get rid of wastes. The delivery of nutrition and oxygen is provided by the umbilical cord.

 

4 Week Pregnancy Tips

In order to provide a healthy smooth pregnancy you should:

•Get rid of negative habits right away. This stage is enormously important for your baby, as he/she is developing the core systems and organs now. It’s time to avoid alcohol, smoking and certain medications affecting the baby negatively.

•Tell your partner about your pregnancy. Talk to him about your feelings and express your concerns, so he could understand what you are going through and what to expect.

•Try to build a support group from your friends and relatives. It would be great to consult with women who are mothers already – they can give advice and help you through the changes. 

•Visit a recommended obstetrician.

•Make an appointment to a dentist in your area. Looking after your teeth is very important, as expectant mothers are usually more prone to bleeding gums and caries.

•See about the medical insurance – what it covers and what doesn’t. 

•Try to relax as much as possible.

 

Your diet is quite important, but that doesn’t mean that you are to change your habits of force yourself to eat something healthy you don’t like. Certain foods can compromise the development of an embryo, but it’s more important to focus on the nutrient-rich products and healthy life able to keep your body thriving for the whole pregnancy. Make sure you get enough folate, calcium, zinc, iron and fiber, choose organic foods and don’t try to “eat for two” in order not to gain too much weight. Water should become your best friend now, as early in your pregnancy you need to hydrate your body.

 

The first few weeks of pregnancy play a huge role in the development of your baby. During this stage your body is working hard behind the scenes to help the embryo grow, and a little fatigue is normal. If you want to stay fit, you can make some exercises, but make sure you don’t overdo – now the normal development of your baby is more important, than your figure.
