Thanks for posting your query.
UTI is very common in females as urinary meatus
and anus is very close.
E. coli bacteria is present in stool and infection with this bacteria is very common.
You should consult with physician / surgeon and should go for urine culture and sensitivity test.
You should also go for ultrasound
imaging as sometimes an obstruction may cause stasis of urine with recurrent infection.
You should take antibiotics treatment on basis of urine culture & sensitivity.
