It’s needless to say that women are different, and so the earliest pregnancy signs are different for every woman. Some women notice these early signs of pregnancy during the first week after conception — and some don’t notice any at this stage. But regardless of this, it is very important to know what is going on inside your body at this point when you’re 3 weeks pregnant.
So, the third week of pregnancy has started. It’s a very important period when your pregnancy loses its assumed status and becomes something that actually exists. If egg fertilization didn’t occur in the end of the second week, then the third week is the most favorable time for fertilization. Ovulation should normally occur on the 12th-14th day of the cycle.
The third obstetric pregnancy week is extremely important because it’s now that the active fetus development begins, as well as the migration of the fertilized egg: it’s doing its best to get to uterus asap and make itself comfortable there by getting implanted in the uterine wall firmly.
Besides, third obstetric week of pregnancy is the period when the fertilized egg starts dividing — and at this point a mom-to-be can get two or even three babies instead of one (multiple pregnancy). Sure thing, news about having one baby is a great joy, and as for a multiple pregnancy, it’s twice (or thrice) as joyful, even despite all the difficulties and necessity of scrutinous medical supervision.
3 weeks pregnant: what is going on now?
In fact, the third week of pregnancy is the first week of your fetus’ life. Since the moment of ovulation a mature egg had only 24 hours to have a date with a sperm cell in the fallopian tube. If this doesn’t happen in due time, the egg loses it chance to get fertilized.
So the biggest event that happens on the third pregnancy week is fertilization. During the first days of this week a zygote (that is, a cell that forms after an egg and a sperm cell unite) is still floating somewhere in the fallopian tube without getting attached to its walls. It continues to move towards uterus. As for the embryo, it is powered by the protein connections allocated by the fallopian tubes glands and its own energy. After getting into the uterus and finding a uterine wall, the embryo starts immersing itself into it (to be more specific, into the uterine lining or endometrium). This is what they call implantation. If it’s successful, the embryo will be firmly attached to the uterine wall by the end of the third week, in this favorable and highly nutrient environment – endometrial layer, and after that stable and multilateral connection between the fetus and the mom’s body will be established.
What are the symptoms?
There aren’t any high-profile changes in a mom’s body at this point but many women can notice symptoms similar to signs of PMS. Even some slight spotting may occur, though it’s absolutely normal and not dangerous as for the mother so for the fetus. This is why symptoms of the three week pregnancy are often confused with a period. And sometimes these sensations can be attributed to a passionate desire to have a baby, when women wait for the smallest signs of a miracle, especially in case this baby was so long hoped-for.
More often than not women notice such symptoms as a slight dizziness, drowsiness, drawing pain in the lower abdominal, insignificant breast swelling. But in most cases future moms hardly have any idea about their delicate state till 5th or 6th week of pregnancy.
3rd obstetric week of pregnancy is one of the critical periods of the entire pregnancy marathon. It is very important to keep yourself safe from stressful situations, overstrain and hard physical labor not to put your future baby under any risk. It’s also important to avoid taking any potent drugs (antibiotics are a special no-no). At this stage fetus’ internal organs begin to develop, so you must be safe from any negative factors from the very first days of your pregnancy.
So now you are on your third week of obstetric pregnancy which, at the same time, is the first fetal age week. This is the time when you can rightfully be called a future mom — even if you don’t really feel it. You have made one step of this exciting and difficult marathon but there is still so much ahead. Don’t forget to consult your doctor and take good care about your health, because a healthy mom means a healthy and happy baby!
Your future baby
On the third week of pregnancy your future baby is really tiny. At this point it’s nothing more than a group of cells bearing important genetic information.
However, embryo formation and development is in high gear. By the time the third week of pregnancy passes, an embryo will look like a hollow sphere 0, 1 – 0, 2 mm in diameter, and the number of cells in it will reach 250. At this time the embryo is placed in a tiny sac filled with amniotic fluid. So far it receives all the nutrient materials it needs not from the woman’s body but from the umbilical vesicle — it’s where the blood formation takes place.
