6 Weeks Pregnant: Signs and Fetal Development

    Fetal Development

    Congratulations! You are already 6 weeks pregnant! You are curious about fetal development and how your baby grows. As well as you might experience some new or more feelings and changes in your body at this stage of pregnancy. While doctors divide pregnancy term into weeks (according to obstetric estimation pregnancy lasts 42 weeks) future moms count every day passing.

    When you learn you are pregnant, you can’t help feeling really happy. The little miracle growing inside you transforms your body. Brand new sensations you have never experienced before appear. Hormones make your mood change abruptly. Your baby grows literally by the hour.

    6 weeks pregnant or 4 weeks since conception

    When an obstetrician tells you that you are at the 6th week of pregnancy, it actually means that 4 weeks has passed since the moment you’ve conceived your baby. The sixth week is when the tiny heart starts beating. It can’t yet be heard during stethoscope examination, but your doctor will be able to see a pulsing dot on an ultrasound machine screen. Its rate is 150 beats per minute — twice faster than an adult person’s heart! Significant changes happen inside your body, and hormones are to blame.

    Hormonal changes in your body

    They happen every single day. Your body works intensely on producing the progesterone hormone it needs to protect the baby from all kinds of infections. This natural chemical enforces the uterine lining providing the intensified blood supply for the baby. But at the same time, the excess of progesterone negatively affects digestive system by slowing digestion and causing nausea and vomiting. This is what they usually call gestational toxicosis.

    Signs of pregnancy

    This pregnancy week is often marked by some not so pleasant symptoms. Some of them can make you feel worried — for example, scanty brownish spotting. But if it’s not abundant and you don’t feel constant pain in the lower abdomen, you shouldn’t be too anxious. This is just a way your body reacts to changes in your endocrine profile and it’s absolutely normal.

    So, there are following symptoms you may notice during the 6th week of pregnancy:

    — excessive salivation;
    — fatigability;
    — frequent urination;
    — abrupt mood swings;
    — nausea and vomiting during morning hours;
    — in some cases, you may experience some soreness in the lower abdomen;
    — the feeling of weakness in your muscles;
    — heavier breasts.

    It should be noted that not every woman expecting a baby has all of the above-mentioned signs during the 6th week of pregnancy. About one third of all pregnant women can’t feel anything out of usual during this period.

    What can a future mom feel?

    Apart from the absence of periods and marked symptoms and signs, your breasts grow bigger now and due to this, you may feel certain soreness and notice that your nipples get somewhat darker. Some unpleasant sensations in the lower belly area are possible too — these are caused by the changes happening inside your womb.

    The hormones make you experience new sensations. You get more sensitive to smells: some of them may even annoy you or cause nausea. The sixth week is when you may find yourself having unpredictable food preferences. Sometimes you can feel dizziness and weakness, and your body temperature rises. It’s most likely that all of these sensations will go away by 10th to 14th week of pregnancy.

    Your baby

    Your baby is as big as a peppercorn now, her height is about 2-4 mm. The nervous system is forming fast from the nerve cells to the brain. Rudiments of tiny arms and legs start forming too — and by the end of this week, it will even be possible to recognize the rudiments of the fingers and toes.

    Your baby face develops some features now: small dimples where his eyes will be and tiny wrinkles in place of the nose and ears. Nervous system is not the only one that develops during this week of pregnancy — muscular tissue starts forming too, and this is why your baby starts being sensitive to external irritants.

    Blood starts circulating through your future baby’s body. Internal organs start forming: stomach, lungs, spleen, some rudiments of bone marrow and cartilage, intestines (it already has three loops), rudiments of the esophagus.

    Ultrasound examination

    Ultrasound examination during the 6th week of pregnancy will definitely confirm you are pregnant. Now your uterus is enlarged, the baby’s heartbeat can be easily recognized and heard. The embryo’s size is about 4 mm and the ovum size is about 25 mm.

    Is there anything to worry about?

    You should be wary of any uncharacteristic spotting that may appear during this period and go see your doctor in case you notice anything like this. Colds, fever, accidental falls and hot baths can pose a threat to your pregnancy as well.

    It would be better if you eat small portions of food. Your meals should contain proteins and vitamins, seafood and dairy products. Don’t ignore your desires, even when they seem odd: they may appear because your body lacks something and needs you to replenish its supply of certain minerals and vitamins.

    Having sex is absolutely acceptable during this week of pregnancy if there’s no miscarriage threat.
