left the ER with no answers 😡

Ugh. I'm so mad right now. We went to the ER because even though I have a subchoronic hemmorage, I stood up and thought my water broke, there was a big gush of something.. it was bright red blood. Literally just pouring out. I soaked through 10 of the big maternity pads within one hour at the hospital. When I stood up, blood would just pour and pour out. They called my doctor, did blood work and checked the baby's heartbeat. Then sent me home. It's the next morning and I'm still bleeding. Not a lot but it's there. I'm so concerned about my baby but the hospital refused to do anything. I thought if it was more than a pad an hour.. they didn't check my cervix, no ultrasound, nothing. No IV to at least give me fluids since I was losing so much blood. As they were discharging me, I stood up and gushed a bunch of blood, their bed needed changed multiple times because of it. Yet they did nothing..
I'm 19 weeks and I have NEVER bled bright red blood this pregnancy, only dark brown blood.
