Thrush again!? 😩

I've had a bladder infection that caused thrush the second day of taking the antibiotics, I treated the thrush whilst I was on the antibiotics (cefalexin) and it seemed to settle down. I finished the antibiotics on Wednesday last week after taking 3 everyday for 7 days and thrush symptoms began to appear again on the Wednesday night! My doctors office told me to treat again for thrush at home with a prescription so I did and symptoms leveled out. It's now a week later and it feels like I've got thrush AGAIN 😭 I could literally cry! I don't know what else to do, the itching is unbearable 😩
