Weeks of pregnancy, months

Despite the fact that gynecologists use pregnancy for weeks and not months, the fact remains that by tradition the pregnancy lasts nine months, of waiting, emotions, fears and adrenaline that rises more and more until the fateful moment of the approaching date of the childbirth. And every month it has its precise characteristics, in the first three months there is the discovery of the positive pregnancy test, the first beta Hg that always put us a little scared, the first ultrasound in which we hear our baby’s heartbeat for the first time and the first tests to do, three months in which there is always the fear that the pregnancy suddenly stops due to a miscarriage and in which the nausea can be really annoying. The second quarter and it is a beautiful time, one has not gained too much weight, one begins to communicate the news to friends and family, one feels good because the nausea has passed and one begins to think about the name of the child. It is also the period in which important examinations are carried out, such as morphological ultrasound or amniocentesis and thanks to which we will discover the baby’s sex. The last quarter is perhaps the most tiring, the belly is large, the baby begins to weigh, we feel more tired and fatigued and it increases more and more the desire to hold our baby in our arms.

Weight in the weeks of pregnancy

It is very important to maintain proper weight during and 40 weeks of pregnancy. Putting on too many pounds not only tires the future mother more, but can increase the risk of Precambrian, excessive birth weight, caesarean section and diabetes. On average it is advised not to put on more than 12-14 pounds during the nine months, and in the first weeks of gestation there is no reason to put on weight. Even if you have an uncontrollable desire to eat and nibble something, try to put a stop to it and treat your diet by favouring healthy and balanced foods that are not too rich in sugar and fat. Recall that in the first quarter the weight gain should be negligible, while starting from the twelfth week of gestation we will begin to take 400-500 grams per week. With our correct weight calculator you can understand how the pregnancy proceeds and if we are putting on too many pounds.

Symptoms of pregnancy

What are the symptoms of pregnancy and when do they appear? Menstruation is late and you can’t think of anything else. Are you or aren’t you pregnant? The best way to dispel any doubt is to take a pregnancy test, of course. But how to recognize the first symptoms of pregnancy and how to distinguish them from premenstrual symptoms?

When pregnancy symptoms begin

As stated on the website Pregnancy Symptoms, the symptoms of pregnancy in the first week vary from woman to woman and depending on the pregnancy, the first is the non-arrival of menstruation. We see the other signs that can occur in the first days or during the first month of pregnancy. But be careful, you may be pregnant without having any of these symptoms, which may appear later.

Symptoms of pregnancy before the cycle

Before the incoming cycle and immediately after conception,  we can perceive the signs of a pregnancy in progress, caused by the hormones that are activated following the fertilization of the egg . For example the hormone Beta hCG , which determines the positivist of the pregnancy test, is responsible for some transformations in the woman’s body. Here are the main symptoms of pregnancy before the cycle :

Breast and abdomen tension

Lower abdominal pains

Blood loss

Excessive tiredness and exhaustion

Nausea and different sensitivity to smells and tastes

Tendency to urinate more often

Increased basal temperature

Now let’s look at all the symptoms in detail, starting from the most reliable one, the only really safe one, namely the lack of menstrual cycle.

The gonorrhoea

Gonorrhea ( absence of menstruation ) is the most important and significant sign of an initial pregnancy, especially if your cycle has always been regular and you have had fertile relationships .

Embryo plant losses

In about 6-7% of all pregnant women blood loss and pain can occur similar to the normal menstrual cycle, but which instead are caused by the embryo nesting in the uterus . However, blood losses rarely take on a menstrual-like rhythmic nature, that is, they occur for several months in a row.

Breast tension

Often this symptom is confused with the classic premenstrual turgor. The breast turgid can also manifest itself several days in advance from the day of the missed menstruation. And then, as the first few weeks go by, the breasts can swell up and become increasingly turgid and tense due to the action of progesterone, sometimes it can give you some nipple pain and irritability. The veins of the breasts are more evident. The alveolar can become darker and small surfaces can appear on its surface, the so-called  tubercles of Montgomery, or glands that in lactation will secrete a lubricating and disinfectant substance

Fatigue

It is a very common symptom and can make you suspect an initial pregnancy, especially if fatigue arrives unexpectedly and distorts your daily habits (you can’t see the end of a movie, you fall asleep after dinner) and above all if you are usually not particularly subject.

Abdominal heaviness

It is a symptom that does not mean much if it occurs alone. Abdominal tension, heaviness, swelling, will be due to the very first hormonal changes that develop with the implant.

Constipation

If you have always been regular, you will be able to observe some constipation even before the expected date of the arrival of the cycle.

Odor sensitivity

It is possible that initially a particularly pleasant smell or that you were used to hearing gives you sudden discomfort, may give you a feeling of disgust and / or nausea. Maybe you will not pay any attention to them, but once the pregnancy has been ascertained you can link that episode to the fact of being pregnant. It often happens with coffee, nicotine, fish, but also perfumes and deodorants.

Nausea

Nausea and vomiting are two of the most common and frequent symptoms of pregnancy, more or less 50% of pregnant women suffer from it. For some women, nausea is the first sign of pregnancy, felt even before the missed period. They generally end after the first trimester of pregnancy.

Frequency to urinate more often

Very common symptom in pregnant women that can occur as early as a few days before the missed period. This discomfort is more frequent from the third trimester, when the child weighs more on the bladder. However, many future mothers complain of more frequent urination in the first few weeks.

Temperature increase

The persistence of the raising of the basal temperature (value close to 37 ° C) from the second half of the cycle to beyond the period of concomitance of the missed menstruation, is a very sure signal of the conception happened, obviously works only if the temperature is monitored by the beginning of the cycle, otherwise the actual rise cannot occur. This is caused by the persistence of the corpus luteum after conception, with the consequent increased secretion of progesterone, to keep your body temperature slightly higher.
