Has she had any other signs of infection like a temp? Could be an infection, when my son has any fishy dinners like tuna or salmon his urine smells fishy the next morning but clears, no signs of infection for him or redness etc so it could be worth mentioning to GP especially if you’ve noticed some redness down there
Ring a GP?
She could have a uti bless her
I would definitely ring a GP as it sounds like she could have a possibly infection or UTI. X
Could be infection and dehydration check gp for advice
