3 Weeks Pregnant – Signs, Symptoms and Embryo

3 weeks pregnant

Now you are 3 weeks pregnant. This crucial week transforms your pregnancy from the stage of “planning” into the real existence. If fertilization has not occurred at the end of the second week, the third week – is the most favorable time for conception. In theory, ovulation should occur on the 12-14th day.

The 3d obstetric week of pregnancy – is an extremely important period, because this is when an active development of the fetus starts together with the migration of the egg, which aims to get into the uterine cavity as soon as possible and permanently settle down there, attaching to the wall.

In addition, the 3d week of pregnancy (obstetric) – is a period of division of the fertilized egg, consequently, an expectant mother can become pregnant with twins and sometimes triplets. Of course, even one baby – is a great joy for parents, and a multiple pregnancy – is a double or even triple happiness for the whole family, though it causes some difficulties and requires a careful medical supervision.

3 Weeks Pregnant: Signs and Symptoms

dizzinessThere are no strongly marked changes in the body at this stage, but many moms can observe some symptoms, which are in many ways similar to the symptoms of PMS. Being 3 weeks pregnant, some women may have slight discharge, which is not dangerous either for the mother or the fetus. Therefore,  the symptoms of pregnancy are often confused with coming periods.

Being 3 weeks pregnant, women often observe the following symptoms: dizziness, drowsiness, a nagging pain in the abdomen, a slight swelling of the breasts.

Feelings

The gestational age is still very small, just a few days. During this period an expectant mother doesn’t feel any changes happening. However, some women say that they feel the moment of the birth of a new life. Perhaps these feelings are caused by a continuous expectation of the first signs of pregnancy, if it is planned and long-expected. But many expectant mothers do not even know about their situation up to 5-6 weeks.

What is happening inside of you?

3 weeks pregnancyThe 3d week of pregnancy – is the first week of life of your fetus. After the ovulation the egg had only 24 hours to meet with sperm in the fallopian tube. If this does not happen in time, it will lose the ability to fertilize.

Therefore, the most significant event of the 3d week of pregnancy is considered to be fertilization itself. In the early days of this week the zygote is still in the cavity of the fallopian tube, which is not yet attached to its wall. It continues its ongoing movement towards the uterus. As for the fetus, it is fed with the proteins, released by the glands of the fallopian tubes, and with its own energy reserves. Having moved into the uterine cavity and having got into it’s inner shell, the embryo begins to plunge into the uterine wall, into the endometrium layer. This process is called implantation. If everything goes well, by the end of the third week the embryo is firmly anchored in a favorable and nutrient environment – in the endometrium layer, and from this moment the durable and multilateral relations between the mother and the fetus set.

3 Weeks Pregnant Ultrasound

At this stage it is possible to determine the uterine pregnancy using a transvaginal probe. Therefore, such early ultrasounds are done just to establish the fact of pregnancy. During the procedure the doctor may also identify a number of symptoms which can threaten your pregnancy.

Fetus on the Third Week of Pregnancy

At the third week of an obstetric pregnancy your future kid is still quite small. It’s just a group of cells that carry important genetic information.

However, the process of formation and development is already underway. When you are 3 weeks pregnant, the fetal size will resemble a hollow ball with a diameter of 0.1-0.2 mm, the cell number will increase to 250. At the third week of pregnancy the embryo is placed in a tiny water pouch, filled with the amniotic fluid. It still receives nutrients not from the woman’s body, but from the yolk-sac. The process of hematopoiesis is going on there.

Safety – First!

The 3d obstetric week of pregnancy – is one of the critical moments of its course. For a week after the ovulation it is very essential to guard yourself against stress, fatigue, and strenuous exercise, so as not to put an incipient life at any risk. It is also important not to take potent drugs, particularly antibiotics are contraindicated.

At this stage, the internal organs of a fetus are being formed. Therefore, it is important to protect yourself from any negative factors in the first days of pregnancy.

      Hi, Marian!
      Some of the early pregnancy symptoms are very similar to those of PMS. Your bleeding could be a normal monthly period.

    Dr says I’m 3 to 4 weeks pregnant, had 2 hcg tests ran, 1st said pregnant, 2nd hcg went down but I’m still pregnant. 1st ultra sound couldn’t find sac, 2nd was vaginal ultra sound , fouls a really small sac but Dr thinks it’s not gonna turn into normal pregnancy and says I’ll probably miscarry on my own, if not then next visit she wants to consult other methods of termination… I believe it’s to early and this could turn around I’m trying to get in somewhere else for 2nd opinion. Is the Dr right? Also I should include I’ve been bleeding this whole time like reg menstrual only a lot of back pain tho… plz help

      Get 2nd opinion. All bleeding isn’t bad unless it is hard bleeding followed by cramps ect. I bled when I was pregnant and my son is 10 now and I have an year old and pregnant again. Good luck

    Iam 46.
    I had my last period on Jan 26.
    I had unprotected sex on Jan 31. I took an ipill on Feb 2.
    I was to have my periods on Feb 24 and March 25. I did not have my periods for Feb and March months.
    I did 3 home pregnancy tests and they were negative. I then did beta HCG tests twice after consulting with doctor. Even that was negative. I had a brown discharge about 2 weeks after taking ipill. My breasts felt tender and itchy. I had stomach cramps in March 2nd week.

    The doctor has prescribed primolut n for 5 days…twice a day.

    I’m worried because I heard this medicine postpones periods. And read about a lot of side effects.
    Am I pregnant? What must I do to get my periods.

      Hello!
      You’re hardly pregnant, considering all these negative results. However, only a health professional can tell you why your periods have suddenly stopped. You’ve told that you did consult a doctor – did they come up with any assumption?

    I could need some reassurance. Last Thursday I had three positive test. I went to see my doctor and he said he can’t see pregnancy, just thick uterus and something that appears as a yellow body on the right ovary. He told me to see him tomorrow because he suspects it could be ectopic pregnancy. I have no pain, just slight, not specially painful cramping. Could it be only too early to see on an ultrasound?

      Hi Sumeja!
      Try not to worry too early. If the doctor suspects it’s an ectopic pregnancy it doesn’t mean they’ll confirm one. Sometimes even doctors are wrong. Let’s hope that everything is okay with you and your baby will be born in perfect health!
