Some women may experience fetal instability during pregnancy, which can easily lead to threatened miscarriage. So pregnant women should be careful in their daily lives and undergo prenatal check ups on time. After discovering abnormal situations, timely measures should be taken to protect the fetus, and more bed rest should be taken. So, when does threatened miscarriage occur?
Threatened miscarriage mostly occurs in the early stages of pregnancy, before 12 weeks of gestation, characterized by irregular vaginal bleeding and accompanied by abdominal pain symptoms. If a pregnant woman experiences the above situation, she needs to seek medical attention immediately, usually requiring a color ultrasound examination to determine if there is a heartbeat.
There are many factors that can cause threatened miscarriage in women, and the most common reason is low levels of progesterone in the body. If pregnant women have insufficient progesterone in their bodies, it can lead to fetal instability and even threatened miscarriage. At this time, pregnant women need to take timely measures, such as oral or injection of progesterone, which has a good effect on protecting the fetus.
Some pregnant women experience threatened miscarriage due to chromosomal abnormalities in the fetus. When there are problems with fetal chromosomes, it can affect development and easily lead to threatened miscarriage, fetal arrest, and other conditions. At this point, there is no need to protect the fetus, as it is a natural choice. Even if the pregnancy is successfully preserved, the embryo will not be healthy.
