When someone's having a moderate to severe flare, waking up at night is common - at least it was for me, as I was getting up several times at night. I didn't find out that I was severely anaemic till I had a blood test done.
From what I know, simply put, the significance of getting up at night is that you have severe inflammation and any slight irritation or activity in the intestine triggers the immediate urge to have a BM.
Can you not request an appointment with another physician or get them to see this as an emergency? I would not hold off till next month to see a physician as it'll just prolong your suffering. I was in a similar position and realize now that I should have addressed things aggressively a lot sooner.
All the best and hope you get this addressed by a specialist soon.
