What is this?!?

I am 31 weeks 1 day as of today. Have been in the hospital twice to stop premature labor as recent as this past Friday night. Went to the hospital after waking up covered in blood. No answer as to why I was bleeding but was told to continue bed rest and the bleeding should stop after a few days. Well this came out this morning and looks like it is gummy bear consistency. I am waiting to here from the doctors office but wondering if this is possibly part of my mucus plug.
