This is because a woman's body suffers from various changes, including changes in blood composition:
- Incease in the synthesis of coagulation factors
- Increased resistance of activated protein C
- Decrease of natural anticoagulants such as protein S
- More venous stasis
All these variations lead to the production of thrombin, which can trigger a thrombosis in the vessels of the placenta and halt fetal development.
