Week 3 of pregnancy

Congratulations, during this week you will conceive your baby and your pregnancy will officially begin. What changes occur during the third week of pregnancy?

Third week of pregnancy. The most important:

You are in the third week of pregnancy. !! Congratulations!! You have already conceived your baby although you don’t know it yet.

Week 3 of pregnancy (Week 1 of pregnancy).

Do not forget to follow a varied and balanced diet, rich in foods with folic acid (green leafy vegetables and legumes), calcium (dairy and nuts), and foods rich in iron (meat).

It is still too early to take a pregnancy test. There is still a week left for you to realize that you will have an absence.

!! Congratulations!! After having had sexual intercourse during your most fertile days of this period (remember, if your menstrual cycle is regular and lasts 28 days, you have ovulated 14 days after your last menstruation, so your fertile period has been 3 days before and 3 days after ovulation day), a sperm has found your egg after a long journey and great effort, and has fertilized it.

A few days after fertilization, the embryo begins its journey from the fallopian tube (place where it has been fertilized by sperm) to the uterus,

In fact, many times ovulation actually occurs between the end of the second week of pregnancy and the beginning of the third.

The development of the embryo in the third week of pregnancy

Once the ovum is fertilized by the sperm, their nuclei fuse. It is in this nucleus where we find the genetic material of both the mother and the father. And around 20 hours after fertilization, the zygote (the fertilized cell) has started dividing, and then continues and continues to divide over and over again.

In a short time after conception, the future baby begins its journey from the fallopian tube to the uterus, while it continues to divide and its number of cells continues to increase.  Now it has gone from a microscopic cell to a ball of cells, known as a blastocyst.

At the end of this week the embryo reaches the uterus. And how is this tour produced?  Thanks precisely to small contractions carried out by the muscles of the fallopian tubes, in whose walls we find millions of cilia, which are small hairs that move in the same direction and that help the embryo to travel through this tube.

Progesterone, which is a hormone secreted by the ovary after ovulation, is also important during this stage, since it helps the sphincter relax, allowing the embryo to pass through the fallopian tube more easily. And the uterus. In addition, it is essential because it increases endometrial receptivity, preparing the uterus for the implantation of the embryo.

What happens in your body during the third week of pregnancy?

It is still too early for big changes to take place in your body, especially the most visible ones. However, it is possible that some of the first symptoms of pregnancy begin to appear mainly due to the different hormonal changes that begin during the first days of pregnancy. And what are those symptoms? The most common are the following:

  • Tenderness in the breasts, with the appearance of some pain and an increase in temperature.
  • Fatigue. The desire to sleep increases.
  • Mood swings and irritability.
  • Greater perception of odors.
  • Increased salivation and taste alteration.
  • Increased urge to urinate.

Therefore, although some of these first pregnancy symptoms may appear, the most common thing is that at the moment you do not notice any drastic or obvious change in your body.

In fact, we must bear in mind that there is still a week left for your period to arrive. So, if your pregnancy has not been planned, it is likely that you do not even think that you may be pregnant.
