subchorionic hemorrhage

hey ladies! I started bleeding and cramping really bad Sunday around noon (this is my third pregnancy)…by the next day it got a lot worse. I went to the ER and they told me I have a subchorionic hemorrhage. I’ve been freaking out all week bc even though it’s common in early pregnancy….I’ve been bleeding like crazy, and literally passing blood clots, like HUGE ball sized clots. I’ve been in so much pain and obviously there’s nothing to do about it besides wait it out. The doctors at the ER told me that even though it’s common, and a lot of women have healthy thriving pregnancies, it can still lead to miscarriage and that’s my biggest fear. I never had this happen before in my other two pregnancies or even heard about this stuff before. My body’s really just going through it. I’ve even lost 5lbs since Monday 😳 any advice or knowledge on this ? has anyone had it before previously? when did the bleeding stop? also at the ER, they said baby’s heart rate was 155 🥺♥️
