First Pregnancy Trimester. 0-3,5 Months

14-21 days of pregnancy. This is the time when the attachment of the ovum takes place in the uterine membrane, and this process can be broken if the uterus has any defects. The reason for termination of pregnancy at an early stage could be uterine fibroids or abnormal embryonic development.

8-12 weeks of pregnancy are the time when the placenta begins to grow and develop. If you have any hormonal disorders that do not allow to form the placenta, it will possibly cause a miscarriage.

Second Pregnancy Trimester, 3,5-7 Months

18-22 weeks of pregnancy. This is the period of an active growth of the uterus. During this period, infectious diseases and sexually transmitted infections are especially dangerous. They violate the function of the placenta and infect the membranes and the amniotic fluid.

If cervical incompetence has been diagnosed, the uterus isthmus and the cervix can not resist the intrauterine pressure and retain the growing fetus in the uterus until the time of delivery. The fertilized ovule moves down, the cervix opens, and there is a spontaneous miscarriage. To resolve this problem before the beginning of the second trimester, the doctor makes a special seam in the cervix.

Third Pregnancy Trimester, Week 28-32

During the third trimester, there is another critical period, which occurs from the 28th to 32nd week. The main causes of premature birth or fetal death are late preeclampsia, placental insufficiency, or placental abruption. These conditions can lead to premature delivery and fetal death. The children born during this period are very premature and require special equipment and care.

How to Behave If You’re in the Risk Group?

The women, who are particularly at risk, should take care of themselves at critical periods, exclude physical activity and try not to worry. Constant medical control and following the doctors’ advice will help you go through these difficult times and become a happy mom!
