Help ladies! Sorry for the graphic nature of picture!

Today at 12:00 I had a doctors appt and he checked my cervix. Said I wasn't dilated, but it was very soft and his head was right there. I left, got to work and went to per and noticed k had soaked through my panties/shorts with bright red/brown blood. Called both my OB and my high risk and I was told to head to L&D just to be checked and monitored. I was at the hospital for a little over an hour, contracting but not unbearable and not close enough. Sent home on strict bed rest tonight. As soon as I get home, I had to pee again and I wiped and more blood and I think part of mucus plug, or blood clot?? Idk. There was discharge as well. Is it mucus plug? Should I call my doctor back? With my son I lost my plug and had him that night. They don't want my labor getting too far as I'm scheduled for a c-section.
