Pregnancy

Pregnancy calendar: 2nd week of pregnancy (4th SA)


You do not know "officially" still that you are pregnant, but a first important sign - your rules are not at the rendezvous! - lets you hope that perhaps, surely ... a small piece of you two grows up in your belly.

Baby side: an egg is implanted

During this second week of pregnancy, the egg continues to grow in your uterine lining to nest. This is called nesting. The cells that constitute it are divided into two different layers: this is the so-called stage of the embryo (two layers of cells). One of these parts, attached to the wall of the uterus, will become the baby, the other will give the placenta to carry the elements that your baby needs to grow. At the end of the second week, the egg measures 0.2 mm. In principle, it is well fixed in the uterine wall, the process of conception is finished and that of pregnancy begins.

Mother's future: Sleeper, it's you!

You still do not know that you are pregnant, there is no sign to suggest your condition ... except this small delay of your period. So you have doubts and serious even, especially if you are set "like a pendulum"! In addition, for a few days, you have an irresistible desire to sleep!

You plan to do a pregnancy test on the first day of late menstruation. How it works ? It looks for the presence of hCG (chorionic gonadotropin) in your urine. Present in the blood from the tenth day of pregnancy, and a little later in the urine, hCG is a hormone secreted by the embryo, then the placenta. The result of these tests available over the counter (not reimbursed by the Social Security), is 99% reliable, but remains to be confirmed by a blood test.
Council +: do it with the first urine of the morning because they are more concentrated in hCG. The test is positive. You do not know if you should jump for joy, you rush on the phone to call your companion, send an email to your best friend or your mother ... Or keep the news for you alone, a few hours! To you to see according to your mood.

Medical question: hCG, progesterone, estrogen and HLP: what are these hormones for?

During pregnancy, the placenta produces four main hormones: hCG, progesterone, estrogen, and placental lactogen hormone (PLH). In the early stages of pregnancy, human chorionic gonadotropin (hCG) is used to maintain the corpus luteum until the placenta is able to fully secrete progesterone and estrogen. Progesterone allows the embryo to become implanted in the uterus. Estrogen stimulates uterine growth to support the developing fetus. Placental lactogenic hormone (PLH) stimulates breast growth and development for breastfeeding.

Your gynecologist is in direct access for pregnancy monitoring, that is to say that you can consult without going through your referent GP. However, you must have declared your doctor to be well reimbursed.
