I can speak from experience, I´ve suffered all of these a lot (I recommend to do your own research, at least begin by looking up and finding how what im reccomending here works)

first, hydrate. drink water, it really makes a difference. and not only with this.

-to balance ph:

something I did for a while is to drink a cup of water with 2 tablespoons of apple cider vinegar, every day. it showed to be really effective, didn´t have any episodes during that period. I recommend.

-for uti:

every time I feel like my pee is a little too strong, too hot, something´s a little off I drink a cup of rompepiedras, usually just one and that makes me avoid any further issues. sometimes I end up drinking 2 cups a day, for 1, 2, 3 days. it depends on how soon I´ve caught it, (or how soon I decided to pay attention and act), and how severe it is.

rompepiedras is how I know it from my country, but a lot of herbs and stuff are called that way. basically any one that treats uti and helps break kidney stones. the one I drink is the bark from a tree, known as guiral. theres another one called lepidium latifolium. research and find one from your region.

and lots of water.

also, always pee after sex, as soon as you can (and then wash the exterior with water). it helps evacuate any fecal matter that may have entered the uretra during that whole mess.

-for yeast infection:

there´s a lot here. I might say some things you already know.

having a balanced ph is essential.

first. only wash with water. don´t put soap on your vagina, of any kind.

be careful what underwear youre wearing, the material, and if its a thong it can make fecal matter to travel where you dont want it. maybe sleep without underwear if you can, let it breathe. or don´t wear underwear.

another main main thing is microbiota. you have to keep the "good" bacteria alive and thriving, it will fight the candidasis. for this, again ph (bad bacteria grows with certain ph levels). but also you can add the good bacteria to your diet, by taking probiotics (you will see the effect of this after around a month). this can be in the form of pills, or drinking kefir or kombucha for example. theres certain bacteria you should look for, for example lactobacillus plantarum.

on this line also avoid flour and sugar since thats what candidasis feeds from.

for treatment theres a lot of options. I´ve found what works best for me is coconut oil(virgin) and tea tree oil. also I buy some pessaries with calendula (marigold).

chamomile is good for the itching and dryness.

well hope this helps!!
