UTI smyptoms that won’t go away

Patient: It started with a uti infection at the end of May. I have had 3 antibiotics and the last time the doctor told me my urine was clear and the infection was gone. But I still have the urgency of needing to go to the toilet all the time. Can you tell me if this is normal after a uti infection as a friend of mine said my bladder could be irritated. Or could it be thrush. Also I have been told I am premenopausal. I am so upset at the moment because I thought the antibiotics would clear it up.

Symptoms: Pressure and needing to pee constantly
