I have never stopped having sex during pregnancy

As we all know, there is a period of time during pregnancy when sex is strictly prohibited, otherwise it is easy to cause miscarriage. So, will sex during pregnancy cause placental abruption? Let's have a simple understanding of this issue. I hope the following points will be helpful to everyone!

Placental abruption is the key cause of miscarriage for many pregnant women. If you have sexual intercourse in the first three months of pregnancy and the last month of pregnancy, excessive excitement may cause uterine contractions, which may cause placental abruption.

After 20 weeks of pregnancy or during delivery, the normally located embryo partially or completely separates from the endometrium before the fetus is delivered, which is called placental abruption.

The pathogenesis of placental abruption has not been fully elucidated, and its occurrence may be related to the following factors:

1. Vascular degeneration: Pregnant women with placental abruption are often complicated by moderate to severe pregnancy-induced hypertension, chronic hypertension, chronic kidney disease, and systemic vascular degeneration. When the spiral arteries of the decidua basalis become spasmodic or sclerotic, the distal capillaries become ischemic and necrotized, and even rupture and bleed. Blood flows between the decidua basalis and the embryo, forming an abscess and causing the embryo to detach from the endometrium.

2. Reflex factors trauma (especially direct impact on the abdomen), external fetal position correction, fetal umbilical cord
