Methods to detect pregnancy at an early stage include tests, tests, and ultrasound. The choice of method depends on the term: some are indicative only at certain stages.
Ultrasound. It is usually carried out after a visit to the gynecologist if the pregnancy is confirmed. It gives accurate results, is informative and is used as one of the main diagnostic methods. The study is planned to be carried out several times to track the development of the fetus: for example, at week 6, during an ultrasound scan, you can hear the baby's heartbeat. For the first time, the gynecologist sends for this procedure only if other factors suggest pregnancy. An ultrasound examination can detect a fetal egg, assess its size and condition. It is not recommended to use ultrasound as an independent method, the procedure is carried out in combination with other methods to obtain a complete picture of what is happening. Before carrying out it is necessary to address to the gynecologist.
Pregnancy test. Many manufacturers offer affordable and easy-to-use tests that supposedly allow you to track pregnancy in the first days after conception. In fact, before the implantation of the fetal egg, this is almost impossible: such tools become informative at least a week after conception. It is then that hCG appears in the blood and urine - a hormone-marker of pregnancy. Before using the test, you must:
• make sure the current expiration date;
• follow the instructions given in the instructions.
Blood for hCG. Among all the analyzes, this one is considered reliable and at the same time accessible. The hormone hCG (human chorionic gonadotropin) begins to be produced by the female body immediately after conception, but its level becomes noticeable about a week after the implantation of the fetal egg. In the blood, its concentration is higher than in the urine, which increases the information content of the analysis. As a rule, the gynecologist sends the patient for examination if there is a possibility that she is pregnant. The analysis can be carried out independently with the help of specialized medical centers, but it is recommended to do this under the supervision of a doctor - he will be able to analyze the results and give the patient a detailed answer about her condition. Diagnosis should be done no earlier than a week after the intended conception.
