The cause is still unknown but a subchorionic hematoma usually happens due to the dislocation of the placenta during the first twenty weeks.

Subchorionic Hematoma

When you’re pregnant, your fetus is well-protected and enclosed within multiple membranes. The layer that surrounds the embryo is called the amnion and the layer that connects the embryo with the wall of the uterus is called the chorion. 

Any bleeding beneath the chorionic layers is called a subchorionic hematoma. 

Thus the bleeding continues and accumulates between the chorionic layer and uterine wall leading to a hemorrhage and eventually hematoma. Its symptoms are:

A subchorionic hematoma is usually seen in the first 20 weeks of gestation typically and when it is observed within two weeks of gestation, it is referred to as implantation bleed.

LargeMore than 50% of the size of the sac

Causes 

The cause is still unknown but a subchorionic hematoma usually happens due to the dislocation of the placenta during the first twenty weeks. The placenta fixes the embryo to the uterine wall and it might get detached causing bleeding and leading to subchorionic hematoma. 

Some other causes are: 

  • Uterine deformity 
  • Trauma 
  • In-vitro fertilization 
  • High blood pressure
  • History of pregnancy losses

The subchorionic hematoma miscarriage rate was once studied in a research in which 13/44 women with subchorionic hematoma faced miscarriage whereas 25 out of 198 women with normal pregnancy experienced miscarriage. So, 30% of women experienced pregnancy loss with it. Hence, subchorionic hematoma increases the chances of miscarriage during pregnancy. 

Signs Subchorionic Hematoma Resolving in Pregnancy

Usually women get confused between subchorionic hematoma and spotting because during pregnancy most women bleed in the first two trimesters. However, spotting doesn’t involve heavy bleeding whereas subchorionic hematoma does. In fact, to cope with bleeding, sometimes you might even have to use panty liners. 

One of the most significant signs of subchorionic hematoma resolving is the reduction in bleeding. It gets limited to a little dark red/brown discharge that eventually goes away as soon as the healing process is completed. 

However, if you start bleeding less, then it does not mean to forget the precautions. You need to be even more careful now because you’re on the verge of healing. Avoid intense exercises, lifting heavy objects, and all kinds of chores. Avoiding sex and complete bed rest are recommended.
