Frequent UTIs aren't only about public washrooms. Wiping direction, holding urine too long, and intercourse can all play a role, so staying home doesn't fully protect against it. Itching in the vaginal area alongside this could also mean a mild yeast infection, which often happens together with repeated UTIs.
Next Steps
Get a urine culture done during an active episode to confirm the exact bacteria, and ask your gynaecologist about checking for an underlying cause if this keeps recurring three or more times a year.
Health Tips
See a doctor sooner if you notice fever, back pain, or blood in your urine, as these can mean the infection has spread higher up.
