Green mucus poop

Kelly
EVF for 9 weeks. About 2 weeks ago her poop went from yellow to green and got more and more slimy and liquidy. She is very happy, spits up occassionally and doesnt seem to gassy. Two recent diapers have had 2-3 small streaks of blood. I am calling the doctor first thing in the morning but wondering if anyone has experienced this. She nurses every 1.5-3 hours and satisfied with one side (5-10 minutes on average) and gaining weight well - born 7lbs now 9.6.
