Uti?

Hi, ive recently had/having what seems like a few uti's but my samples come back clear but im left with very cloudy urine at the end of cathing (just the length of the catheter) and i cant hold as much but apart from that im ok, im wondering what would cause these symptoms, i think my botox has ran out now and my bladder is starting to work again, im trying to think back a few times in the past where my botox has ran out and ive been met with cloudiness but im not 100% but i think it has happened but then i get booked in and get topped up and im back to normal, but this time its been alot longer yet not very long since i got the botox done, has anyone else had this happen to them after botox has ran out?? or just had this happen to them, its driving me mental, thanks
