What are the specific reasons for early pregnancy miscarriage? There are 7 major reasons

Miscarriage during early pregnancy may be caused by insufficient secretion of estrogen and progesterone in the body; it may also be caused by defects in sperm and eggs, and incomplete embryo development; genital lesions, external impact on the abdomen, large mood swings, incompatibility of blood types between mother and baby, and unhealthy lifestyle can also lead to miscarriage during early pregnancy.

For families who are looking forward to the birth of a new life, miscarriage in early pregnancy is a devastating thing. At this time, it is important to understand the causes of miscarriage in early pregnancy and pay more attention to future pregnancies to prevent habitual miscarriage and prevent the dream of becoming a father or mother from being realized. So, what are the specific causes of miscarriage in early pregnancy?
1. Insufficient secretion of estrogen and progesterone <br/>After pregnancy, the fertilized egg needs the action of estrogen and progesterone to implant, grow and develop on the uterine wall. However, some pregnant women do not have sufficient secretion of estrogen and progesterone in their bodies. At this time, the poor development of the uterine decidua will also affect the development of the fertilized egg and easily lead to miscarriage.
2. Incomplete embryonic development <br/>Embryonic development is also a process of survival of the fittest. If there are certain defects in the sperm or egg, such as chromosomal abnormalities, it will often lead to incomplete embryonic development. Such an embryo will stop developing in the early stages of pregnancy, resulting in miscarriage.
3. Genital lesions <br/>If a pregnant woman has uterine malformations such as a bicornuate uterus or a septate uterus, or suffers from uterine diseases such as uterine fibroids or adenomyosis, it will affect the development of the embryo and may cause miscarriage. If you have uterine fibroids or other diseases, it is best to treat them before pregnancy.
4. External impact <br/>Because early embryo implantation is not stable, if the pregnant woman's abdomen is hit or squeezed by external force, it may cause miscarriage. For example, if the pregnant woman engages in heavy physical labor, intense physical exercise, or has too intense movements during sex, etc., she may sometimes have miscarriage.
5. Large mood swings <br/>In the early stages of pregnancy, pregnant women must maintain a good attitude, avoid extreme joy or sorrow, excessive excitement, etc. Otherwise, negative emotions will cause uterine contractions and lead to miscarriage.
6. Incompatibility of blood types between mother and baby <br/>If the mother has received a blood transfusion before pregnancy, or if coagulant factors that are incompatible with the blood type appear during pregnancy, a hemolytic reaction may occur, which may lead to miscarriage of the fetus.
7. Unhealthy lifestyle <br/>Frequent smoking, drinking, drinking large amounts of strong tea and coffee, staying up late for long periods of time, and being frequently in a polluted environment, etc., will all affect the development of the fetus and may cause miscarriage in the early stages of pregnancy.
