I’m 33+4 weeks pregnant, have had multiple kidney and urine infections, in pain?

I’m 33+4 weeks pregnant, have had multiple kidney and urine infections throughout, I have two duplex kidneys so I get frequent infections, I’ve been self catheterising three times a day for the past 6 weeks since my last infection and have also been on low dose cefalexin every day since as a prophylaxis to try prevent another one. I have recently been in hospital for regular blood pressure checks and baby monitoring also because I have just started with pre-eclampsia symptoms and am going in twice a week for monitoring.

I have been in allot of pain with my back in my flank and all across my lower abdomen for months and use dighydrocodine occasionally To try help with the pain, but the flank pains worsened over past three days and I took a dilstick test at home and this showed keystones, glucose, protein, blood and leukocytes in my urine. I have a hospital appointment in two days , can I leave it till then to get checked as my mobility right now is limited and it’s painful remove about or should I get in tomorrow to the emergency doctors?
