first symptoms of pregnancy

Each woman should imagine the first symptoms of pregnancy. Fortunately, the basic symptom of pregnancy - a delay monthly is probable enough sign, however, it is necessary to consider, that the delay monthly not always speaks about pregnancy and can take place at a various gynecologic pathology. At the big number of women menstrual a cycle irregular, that certain degree delivers to them in inconveniences in pregnancy definition. There are in practice such cases when women learnt about the pregnancy already on late terms only because of the expressed infringement menstrual a cycle.

So, on what pregnancy diagnostics is based? All signs of pregnancy are divided into 3 groups: presumable, probable and authentic signs.

1. Presumable symptoms pregnancy pregnancy are subjective sensations of the woman and change in an organism which do not concern genitals. We will notice, that these symptoms of pregnancy are changeable, and their occurrence depends on specific features of the woman:

A.So of the party of a gastroenteric path and food behaviour: a nausea, vomiting in the mornings, change of food behaviour - predilection for sharp and sour dishes. Often enough women start to use dishes which all life refused. Now seldom there is a taste distortion: the desire is a chalk, clay and so forth

B.Izmenenija of nervous system: irritability, isolation, tearfulness. Many women describe an aggravation of sense of smell, hearing.

V.Izmenenija of a metabolism: adjournment of a fatty fabric, pigmentation of nipples, a median line of a stomach, occurrence of pigmentary stains on the person.

2. Probable symptoms pregnancy pregnancy - the changes occurring in internal genitals of the woman, mammary glands, and also laboratory and express tests for pregnancy. As a matter of fact, the further transfer of probable signs is a guide to action for women if they suspect pregnancy.

A.Prekrashchenie menstrual. The delay next monthly for 4-6 days at regular menstrual a cycle speaks about enough high probability of pregnancy. However the delay of the next monthly can occur owing to any infringements in regulation menstrual a cycle. Often it occurs at emotional and physical overloads. Nevertheless, at a delay menstrual it is necessary for woman to make the express test for pregnancy.

B.Ekspress-test on pregnancy is based on definition of "a pregnancy hormone» - in urine. The hormone is developed by an embryo in blood, and deduced from an organism with urine. The woman in house conditions can spend the test: after processing of test system by urine at positive result the second strip is painted over.

Modern test systems allow to define pregnancy with enough big accuracy already about 2-6 days of a delay monthly, however, there are cases of is false-positive or is false-negative results. To avoid similar difficulties, it is recommended to get 2 tests of different manufacturers. In case of negative result, or is doubtful-positive («the second strip») it is recommended to repeat the test in 48 hours and then to address to the expert.

V.Izmenenija in genitals - a uterus, a vagina - is defined by the expert. From 5 weeks of pregnancy (1 week of a delay monthly) the gynecologist, having made vaginal research, can define increase in the sizes of a uterus and change of its form.

G.Pri doubtful results of inspection, and also in some clinical situations (for example, for specification, pregnancy develops, or not) laboratory tests for pregnancy are made: they are capable to define quantity of "a pregnancy hormone» in an organism. For this purpose on the analysis send venous blood of the woman.

3. Authentic symptoms pregnancy pregnancy. When it is possible to find out a fruit or its parts, warm activity of a fruit or its movement the pregnancy diagnosis is not subject to doubt. In medical practice the case when the woman with a delay monthly and the positive test for pregnancy in 3 months has addressed to the gynecologist took place and has learnt, that it is a question not of pregnancy, and about a uterus tumour.

The most widespread hardware method of diagnostics of pregnancy is ultrasonic research. Modern devices allow to diagnose pregnancy approximately in 1-2 weeks of a delay of the monthly.

Definition of localisation of pregnancy is important: in 1 % of cases it can settle down out of a uterus cavity (extra-uterine pregnancy)

However it is not necessary to forget, that you can have all signs and symptoms of pregnancy and, despite it, you can be not pregnant. Or at you can appear only a few from them and you just more all are pregnant. Various signs and pregnancy symptoms is only indexes to which it is necessary to pay attention, but not to expect reception thanking it of completely confident acknowledgement.

Some from symptoms pregnancy which you will notice, can assume pregnancy possibility, others - probability. Any from early symptoms pregnancy are not, however, completely confident acknowledgement of occurrence of pregnancy. De facto, the confident proof of pregnancy first completely is heart beat of your child which about 10th, and is more often 12th weeks it is possible to hear with use of very sensitive device Us-Dopplera, and in case of use of a usual stethoscope of the doctor - about 18th - 20th weeks. Earlier signs assume only possibility or probability, that you carry in yourselves the child. The checked up tests of pregnancy together with medical inspection can help to establish the correct diagnosis
