I was drinking loads and equally passing loads, I thought it was the drinking causing the peeing, as when I was out I could and would restrict my drinking, (although still thirsty), to avoid having to go to the loo all the time.
My doctor did not suspect diabetes as it was 'manageable' - turns out I am T1/LADA at 51, and had a mega HbA1c!
So please get an appointment, there is no rule for 'how much in or out = diabetic', and I'd say all your symptoms are classic and your midwife was completely uneducated, and dangerous in her opinions.
