Yes, I Don't Know How But I Think I've Had

Yes, I don't know how but I think I've had a UTI. The first few days it burned while urinating but my pee also had a very strong odor (unpleasant) the odor disappeared after a few days as well as the need to pee every second of the day but it still burned a bit while peeing. Now 9 days later my clitoris also feels a weird tingle/discomfort at the end of urinating and the burning still remains a bit in the urinary tract. The need to pee constantly also returned. My question is if I can treat this naturally or do I really have to get antibiotics?
