How does a subchorionic hematoma cause a miscarriage? Like how does it actually cause you to lose the baby? What is the mechanism involved? Thanks.

If u have one. It is your ob;s job to explain that to u, it can cause the placenta to separate from the uterine wall so the fetus will have no blood supply, most sub chorionic hematoma in the 1st trimester resolve and do not cause a loss.
