8-9th day of fertilization. On the first day of pregnancy, pregnancy hormone (beta HCG) begins to become positive in the blood. This value approximately doubles every 48 hours. This increase most likely indicates that the pregnancy is in normal location and development. It is most likely that this increase in pregnancy hormone is less than 53% in 48 hours. It is associated with a pregnancy that does not go away. In this case, ectopic (ectopic) pregnancy or miscarriage may occur.
Especially if the pregnancy is located outside the uterus, early diagnosis of ectopic pregnancy requires medical (drug) treatment or surgery. It is also very valuable in terms of the chance of laparoscopic (closed) surgery. Therefore, doctor control from the beginning of pregnancy is very important!
When the pregnancy hormone (beta HCG) level rises above 1500, when it rises above 6000 with transvaginal ultrasound, The gestational sac becomes visible on abdominal ultrasound.
If the pregnancy occurs after late ovulation, the appearance of the gestational sac may be late. In this case, the physician may call the patient for intermittent check-ups if he deems it necessary.
The first heartbeats of the fetus (baby) occur in the 6th-7th week of pregnancy. It begins to appear within weeks. In order to ensure standardization, the gestational week in all gynecology clinics is calculated starting from the first day of the pregnant woman's last menstrual period. The calibrations of all ultrasonography devices are designed accordingly.
The physician may need to re-evaluate the patient depending on the situation for the development of the baby after the heartbeat.
In these weeks, if the immune status detected before pregnancy is not in question, it is useful to determine some infections such as toxoplasma and rubella, which are normally asymptomatic (without giving symptoms) but are teratogenic (potential to cause problems in the baby) when contracted during pregnancy, by blood examination. Here. The importance is the presence of an active infection, not a previous infection.
Pregnant examination between the 11th and 14th weeks is very important. In this examination, the baby's organ formations have been completed to a large extent (organogenesis).11 -14. The nuchal translucency (NT) of the fetus must be measured between weeks and a double test, which is a Down syndrome screening test, must be performed. Seeing the nasal bone (nasal bone) should also be done this week. a is a very important finding.
If the double test could not be performed for some reason in the 16th-18th weeks, it is an opportunity to perform the quadruple test, which is another down syndrome screening test. The quadruple screening test is the second valuable test after the double screening. In addition, it is possible to detect many anomalies of the baby in this week. Because the baby's extremities (hands, arms, legs and feet) are most easily seen in these weeks.
For the first time There is an opportunity to perform a triple screening test during these weeks of pregnancy for patients who apply between the 18th and 20th weeks of pregnancy, or for patients who have not previously had a Down syndrome screening test performed for some reason.
19-21. These are the weeks of pregnancy when the baby's organs can be seen best and a DETAILED AND SECOND LEVEL ULTRASOUND evaluation can be performed best. Therefore, it is very important. After this week, as the baby grows, examination will become more difficult.
22- 23. weeks of pregnancy are the ideal evaluation weeks for fetal heart examination and fetal echo when necessary.
Tetanus vaccination is recommended during pregnancy. Although there may be different applications in terms of dose and timing, it is generally 20-26 weeks. The week range is considered appropriate.
24-28. week range is the weeks when the baby's growth and development should be done as well as the sugar loading test. It is performed for the purpose of screening for gestational diabetes due to insulin resistance that may develop during pregnancy. This test is recommended for all pregnant women, especially those in the risk group. 50 or 75 gram screening tests can be used for this purpose. 100 gram OGTT is performed for diagnostic testing for patients with high OGTT (sugar loading test) results.
Between 28-35 weeks of pregnancy, your doctor may start a follow-up program depending on the condition of the mother and the baby and the presence of any possible problems with the baby's development. In this, possible problems developing in the pregnant woman, the development of the baby, and the follow-up parameters in the fetus, placenta and amniotic fluid are important.
After the 35th week, it is recommended to follow-up NST (non-stress test) weekly until birth. NST determines the baby's condition in the womb, whether it is exposed to stress, nutrition and nutrition, according to certain criteria, in which the baby's heartbeat is monitored as a trace. show the bleeding It is a valuable test. The fact that this test is reactive indicates that the baby is not under stress. This weekly follow-up close to birth is aimed at preventing sudden losses in the womb and other problems that may develop.
Blood pressure monitoring is important during pregnancy. This risk is higher in patients with pre-existing blood pressure. Pregnancy blood pressure (gestational hypertension) may occur in women who have never had high blood pressure. In addition, conditions called preeclampsia and eclampsia, defined as pregnancy poisoning that can be life-threatening for the mother and the baby, may occur. Blood pressure monitoring is very important for early detection and intervention.
The 38th week is very important in terms of determining the type of birth. Ultrasound and examination to be performed this week in cases with first pregnancy; the weight of the baby, the way of presentation, the location of the placenta (the baby's partner), NST and the placement of the baby is examined by evaluating whether the mother's pelvic structure (birth canal) is suitable for normal birth. If there is a condition that prevents normal birth, risks are detected in advance.
If there is no contrary situation, or if the mother wishes or medically If a cesarean section decision has not been taken before due to necessity, the expected delivery date is 40 weeks from the first day of the last menstrual period.
