HELP!!! (Pictures of blood are included)

Taylor
I'm 35 weeks & 4 days. I've been cramping bad for the past 2 weeks. Went to the hospital at 7pm & they said I was 2 1/2 centimeters. They gave me 3 shots (terbutaline) to stop the contractions. It worked for about an hour but they started up again around 11:30. I'm bleeding, cramping, & they sent me home anyways. What should I do?
