The doctor will take the tension to you to verify that it is still normal, and will weigh you again if there was an excessive increase. It usually happens in this visit that the weight has diminished, and it is due to the fact that some women suffer morning sickness during this first stage so that they eat little or are sick. It is not worrying unless it is supported in the following stages.

If you are of more than twenty weeks in this visit the fetal beat will be auscultated so that you could hear the beat of the heart of your baby, which is usually a very exciting experience. The fetal beat has a speed superior to ours. Before twenty weeks it is not listened.
The doctor will observe your hands and feet in search of edemas or distensions and varicose veins.

After this visit you will be put to the following tests:

1. Ultrasound scan: to verify that the fetus and his small ecosystem are normal. In this ultrasound scan the gynecologist will measure the crease of the fetal nape across which it is possible to discard, together with the analyses, the risk of syndrome of Down. The ultrasound scan, ultrasonography or ecosonografía is a procedure of imagenología who uses the echoes of an ultrasound emission directed on a body or object as data source to form an image of the organs or internal masses with diagnosis ends. A small instrument "similar to a microphone" called transducer expresses ultrasound waves. These sonorous waves of high frequency transmit towards the area of the low body study, and his echo is received. The transducer gathers the echo of the sonorous waves and a computer turns this echo into an image that appears on the screen of the computer. The ultrasound scan is a very easy procedure, in which radiation is not used, although it usually realize in the radiodiagnóstico service, and that's why it is used often to visualize fetuses that are forming. On having surrendered to an ultrasound scan examination, the patient simply goes to bed on a table and the doctor moves the transducer on the skin that is on the part of the body to be examined. Earlier it is necessary to place a gel on the skin for the correct transmission of the ultrasounds. It is not invasive test (not dangerous) across which you will see your son on a screen. Normally after 8th week is when it is possible to appreciate. Across this test there can be calculated the fetal age and his morphology (hands, feet, sexual organs, …)
2. Analysis of urine and blood: The determination of biochemical scoreboards in the maternal whey allows to realize an estimation of the risk for the syndrome of Down and defects of the pipe neural. The quantification of the levels of alpha - fetoproteína and Beta-hCG is interpreted according to the age gestacional and is corrected in relation to the maternal weight and the race and later it gets together with the risk of syndrome of Down corresponding at the maternal age. When there is obtained an estimation of risk superior to 1/270 the amniocentesis is considered to be stated. It is very important that this analysis, so called triple test, screening biochemist or cribaje biochemist, is realized in the age gestacional correct that it corresponds to the period between 17 after 15 weeks.
