UTI symptoms, negative culture

I have had uti symptoms for 10 days, 2 visits to ER, thought i might have stones. Negative. Im on my 3rd antibiotic and I feel better. My culture came back negative and my doctor said I can stop my antibiotics. Im not sure i should stop though. Thoughts?

If the culture is clear you can stop like the doctor said , but I would immediately start with preventative measures . I take D Mannose powder 3 times daily , a teaspoon dissolved in water and an extra dose after intercourse . Also , start drinking at least 2 cups of kefir every day , I make mine myself . It’s a lot more potent than the crap in the store . Learn how to make it on YouTube , it’s easy .

The medics are not looking hard enough. Keep on them?
