Subchoronic Hematoma/ Hemmorhage -SCH

Hi everyone. At about 6 almost 7 weeks pregnant I was diagnosed with a SCH. I was put on modified bed rest for 3 weeks. I was having huge, bright red gushes of blood to the point that it looked like I sat in a puddle of blood. The bleeding stopped for a week and a half and I was so excited! Last Friday it Started again, on this time its dark brown blood. Yesterday all day, huge gushes again of dark blood. Just started again tonight. I went to my ob and he said it was measuring 3.2cm by 5cm. I am absolutely terrified of losing our baby. The bleeding is associated with cramps/pressure which also is incredibly concerning. I've been on pelvic rest the entire pregnancy, and also drink a ton of water, no exercise, and no heavy lifting. I'm 11 weeks in two days. I'm so scared. Any positive stories/advice/thoughts? I feel so helpless.
