Retroplacental hematomas are entirely behind the placenta and not touching the gestational sac. Subamniotic or preplacental hematomas are contained within amnion and chorion. Rare. Most patients with a small subchorionic hematoma are asymptomatic. [5] Symptoms include vaginal bleeding, abdominal pain, premature labor and threatened miscarriage. [6]
Implantation bleeding involves a small amount of bleeding that may occur 10 to 14 days after implantation of the fertilized egg. However, there is little evidence to support the existence of such bleeding. [10] Chorionic hematoma is the pooling of blood between the chorion, a membrane surrounding the embryo, and the uterine wall.

Doctors diagnosed a subchorionic hematoma, a condition that causes bleeding between the uterine wall and the amniotic sac. It often clears up on its own, but Bell said she had one of those rare ...
Breus' mole is diagnosed antenatally by ultrasound, where a thick multilobulated hematoma can be seen beneath the chorion. Occasionally, subchorionic thrombohematoma may later become intraplacental, making its diagnosis difficult. The mole may be echogenic or hypoechoic depending upon the amount of fresh blood present in it. [3]
The 34-year-old from Atlanta learned at seven weeks gestation that she had a subchorionic hematoma. According to the Cleveland Clinic , it is a condition in which "blood forms between a baby's ...
Antepartum bleeding (APH), also prepartum hemorrhage, is bleeding during pregnancy from the 24th week [7] (sometimes defined as from the 20th week [8] [7]) gestational age up to the birth of the baby. [5] The primary consideration is the presence of a placenta previa which is a low lying placenta at or very near to the internal cervical os.
Causes of postpartum hemorrhage are uterine atony, trauma, retained placenta or placental abnormalities, and coagulopathy, commonly referred to as the "four Ts": [12] Tone: uterine atony is the inability of the uterus to contract and may lead to continuous bleeding. Retained placental tissue and infection may contribute to uterine atony.
