Pregnancy, achieved as a result of IVF - is not only a great victory and happiness, but also is the beginning of a new joyful and anxious stage. To save and carry a child, unfortunately, do not always succeed. According to the statistics, 20% of pregnancies are interrupted, and it occurs mostly in the first trimester (untill 12 weeks).
Pregnancy abortion can occur as a spontaneous abortion, when the elements of fetal egg are expelled from the uterus, or as a missed abortion,in case if the development of the embryo stops and the ovum stays in the uterus for some period of time. All causes of interruptions can be divided into two major groups: embryonic causes and maternal factors. The first place, according to statistics, occupy those reasons, which are related to gene and chromosomal abnormalities of the embryo. In such cases abortion occurs untill 6 weeks of pregnancy. Also the anembrioniya can occur (no embryo in the ovum). Controlled ovulation stimulation (COS) causes certain hormonal changes in the body of a woman. In order to identify the necessity of hormonal support, control of estradiol and progesterone levels in the blood of women are made. This high level of estradiol is also an indicator of the risk of developing ovarian hyperstimulation syndrome. To support the pregnancy, your fertility specialist selects drugs and their dosage individually. Vaginal and sublingual (under the tongue) form of the applied drugs are used. The important role played the vitamins, especially vitamins antihypoxants (Vit. C and E, b-carotene), folic acid (up to 800 micrograms per day). With burdened obstetric history (fetal malformations) the dose of folic acid from the early period is 5 mg / day.
Ultrasound test for determining the state of pregnancy makes sense to do not earlier than in the period of 3 weeks after transfer. At this time, it is already possible to see the fertilized egg, to assess the condition of the endometrium and ovaries. Ultrasound test is provided according to indications with weekly breaks for dynamic monitoring of the fetus, ovaries and uterus. Also the location of embryo is estimated (poor location can lead to abortion), absence (or presence) of free fluid into the uterine cavity (i.e., blood), detachment of the ovum, etc. All this allows to identify in the early stages the threat of interrupting and take preventive measures. In addition, the key of a successful pregnancy is a woman's constant contact with her attending doctor. Woman should monitor her condition and immediately tell her doctor about the appearance of bleeding, lower abdominal pain, bloating feelings in the abdomen, etc. Multiple pregnancy, the frequency of which during the IVF is very high, always is fraught with the threat of miscarriages and premature births. Therefore, one way to avoid these complications is the selective transfer of one embryo.
It is sad to admit, but women who were in 1st trimester of pregnancy, which was the result of IVF, were observed in antenatal clinics in the community, the percentage of abortion is in three times higher than among those, who spent their first weeks of pregnancy under the supervision of doctors in reproductive clinics.
Your health and safe during pregnancy depends on the correct implementation of the treating doctor, timely notification for your doctor about any changes in your health. With full confidence to the doctor, all joint efforts will be completed with happy birth of your long-awaited baby.
