Sch and weakened amniotic sac

CarolynS2010

hello, I am Carolyn and 20 weeks pregnant with my 4 th child. I had a gush of blood jan6 and ultrasound jan. 16 showed 6 cm hematoma. Gushed blood again on feb.2 and ultrasound from jan.30 showed a 10 cm hematoma. I went to see high risk doctor on feb 11 and I was told that the blood from the hematoma kept my 2 layers of amniotic sac from fusing so now I have a weakened amniotic sac. I am taking progesterone and have been on bedrest since jan 6. Has anyone heard of something similar or had a similar experience?? Google is not my friend on this one.
