Some pregnant mothers are also helpless about the three major factors of abortion. How should we find out?

Termination of fetal birth has the following influencing factors: 1) insufficient secretion of maternal hormones, that is, insufficient luteal function; 2) Chromosome abnormality, leading to embryonic hypoplasia, should be diagnosed through prenatal genetic counseling and related chromosome examination; 3) External environmental factors in early pregnancy, such as physical factors such as exposure of pregnant mothers to chemicals, X-rays, noise, microwaves and high temperature. And the drugs taken have an effect on embryo implantation, which may cause embryo abortion. 4) Abnormal uterus, such as thinness.

The precursor of abortion is usually irregular vaginal bleeding during abortion, and some can also be brown bloody secretions. The ultrasound examination passed, and the embryo or fetus had no fetal heart.
