Those deep thin slippery rapid pulses with tight R3, along with pus and blood in the stool, no menstrual flow, severe abdominal pain, and distended and hard abdomen make me think of treating the blood layer. BTWJGCEJT could be part of what you need if her pulses are expiring and she is thirsty; DHMDPT is a possibility if her urine is regular, she feels hot, etc. Also, I’d consider GZFLW with that deep tight R3, abdominal pain, etc.
