The first month of pregnancy It can be one of the most particular months of the nine that the gestation lasts, since it is possible that a woman barely notices anything during the first month of being pregnant, so that when she knows her state perhaps those first four weeks have already passed. Thus, it is important to know what exactly happens during this month as we explain below.
The first month of pregnancy
As we have mentioned, many women hardly notice or know what they are pregnant during the first month. In fact, the first suspicion will undoubtedly be a delay in menstruation And you may be several weeks pregnant by then.
For this reason, it is important to point out the time involved first month of pregnancy, what it goes from the first day of the last cycle to 4 weeks + 3 days later.
It is also the month that slips away faster than all the others Precisely due to the high incidence of women who, when they realize that they are pregnant, are already at the end of the first month or are fully involved in the second.
In the meantime, however, great changes have occurred because a new life is being formed from a single microscopic cell.
But Why are we talking about the first month when the embryo is actually only 14 days old at the end of the first month? To understand this, we will have to turn to the also confusing subject of gestational period.
Any Pregnancy is calculated or dated from the first day of the last menstrual cycle.
How to count the weeks of pregnancy
In a cycle of 28 days, the first month of pregnancy consists of fifteen days in which the woman would be pregnant but nothing has happened yet. As it happens every month, the follicle that contains the maturing oocyte is formed, which will be expelled from the ovary at the time of ovulation.
In the initial two weeks, therefore, there was no ongoing pregnancy, but it is counted precisely from the date of the last menstruation, because the actual date of conception can be quite difficult to define. Also, before we knew so much about conception, it was known that women (on average) tended to give birth around 40 weeks after the start of their last period. So if you are 1 month pregnant, it means your last period started about 1 month ago (in an ideal cycle of approximately 28 days).
Still on the idea of an ideal 28-day menstrual cycle, being one month pregnant means that conception occurred about 14 days before. So your baby will always be “younger” than what is generally considered one month pregnant. But don’t worry, the entire world of obstetrics and fetal development revolves around gestational age, so keeping that number means staying in line with everyone else’s milestones and expectations.
What happens in the first month of pregnancy?
Usually when you decide to have a baby, you start taking folic acid (something that is essential) and you have had sexual relations aimed at pregnancy. Those who decide to have a baby rarely do not calculate and have sex at will. It is part of the psychology of women to reach the goal as soon as possible after making the decision, so that among other things it is important to take into account the fertile days, that is to say, those days of the menstruation cycle in which it is more feasible to get pregnant.
In this way, after ovulation (we are in the third week), the egg moves into the uterus along the fallopian tube. This is where the encounter and fertilization with one of the couple’s millions of sperm. Once conception has taken place, the resulting cell (zygote) undergoes a series of cell divisions as it continues its journey to the uterus. Is in the timing of the fusion of the eggs and sperm when determining the genetic origin of your baby.
Seven days after leaving the ovary, the collection of cells called the blastula / blastocyst reaches the uterus where it lodges in the wall of the uterine cavity. Not all blastocysts manage to nest in the uterus (estimated at 1 in 10 to a maximum of 1 in 3) and are eliminated by menstrual flow. Conception is completed only when the blastocyst manages to nest in the endometrium.
Thanks to nesting, the embryo that is forming can be nourished by the blood vessels in which these tissues are particularly rich. So too the placenta begins to form (initially it is called a trophoblast) which will allow exchanges between the mother and the fetus throughout the pregnancy. If the endometrium (the inner lining of the uterus) not rich enough in nutrients to maintain the pregnancy, miscarriage occurs that resembles a late and very heavy menstruation without you realizing (unless an early pregnancy test is done) that you are pregnant. Undernourished uterine lining is one of the most common causes of infertility.
In the fourth week, the cells begin to differentiate. A group becomes the amniotic sac where the embryo will grow first and then the fetus, a group specializes in the viteline sack from which the corpuscular part of the blood (blood cells and platelets) will originate, while a third group, the trophoblast, becomes the placenta. Finally, other cells are the ones that will give rise to the baby. In this point, Your period is late and you may be beginning to think that you are expecting a baby. Has arrived the time to take a pregnancy test to detect the presence of the beta HCG hormone.
The HCG hormone
The beta HCG hormone is produced by the trophoblast, and it is this hormone, together with the progesterone produced by the luteum, that allows to support pregnancy at least in the first weeks favoring the formation of the placenta and a whole series of effects that help consolidate pregnancy.
The beta hormone HCG maintains the corpus luteum in the ovary which in turn produces progesterone. Progesterone is essential to maintain pregnancy since it reduces the activity of the smooth muscles of the uterus to avoid the appearance of contractions that could cause a spontaneous abortion. At the same time, however, there is also the (negative) effect on the intestinal smooth muscle that causes constipation, and on the bladder with the consequent feeling of always having to go to the bathroom.
The beta HCG hormone grows progressively in the first weeks causing the classic discomforts such as nausea and vomiting that may be less tolerated by future mothers.
Embryo dimensions in the first month of pregnancy
Regarding fetal dimensions, around the fourth week the embryo measures about 2 millimeters. It is shaped like a small green bean that, however, already has a drawing of the brain and spine.
The first symptom of pregnancy
The late period is the first symptom of pregnancy . However, it is possible that notice also that the breasts are firmer and that you feel like urinating more often. Some women also experience a strange metallic taste in their mouth.
The easiest way to know if you are pregnant or not is to take a pregnancy test , which, as we have commented, detects the presence of the beta HCG hormone. Today you can even buy early tests that are reliable as early as 4 days from your period date. In case the result is positive, congratulations! because you are pregnant and surely from the second and above all, the third month you will begin to notice how all pregnancy symptoms they are reproducing in increase.
