What’s going on- advice needed :(

already diagnosed with CV but here’s my story

Hi! I’m 25 and about a month ago on 2/16 I started getting that itchy/uncomfortable feeling. I used some boric acid (my usual tried and true), with no luck and tried apple cider vinegar as well which has helped in the past with yeast infections. Come to find out I was making it worse (lol).

I decide to book an appt at Planned Parenthood on 2/20 and they tell me to come back since I had inserted the boric acid and that could alter my swab results. Soo I go on 2/22 and finally get diagnosed with CV. I started baking soda douches & did it once a day for three days & it cleared up!!! (Yay!!)- stopped treatment after symptoms stopped

I was symptom free from 2/25-3/6, then my symptoms started AGAIN :( I’ve been doing the baking soda douche and even started applying a paste to the outside for about 15 mins before rinsing it off with warm water. It provides instant relief for a few hours but then the itchiness starts coming back

I did my first suppository last night 3/11 and it helped, but now it’s 1pm and I’m starting to feel the tingle again.

Also worth noting- my doctor confirmed it wasn’t yeast or BV, I also tested negative for all STD/SDI’s. My doctor also said my boyfriend didn’t have to get treated & just to maintain good hygiene which he has. We have refrained from being intimate since my symptoms started again :( any advice for that?

My questions are :

1. WHY did this even happen, I didn’t start taking probiotics or change anything in my routine AT ALL so like…?? Could it be hormonal?
2. am I overdoing the baking soda? Like mentioned, it provides instant relief for a few hours then the itchiness comes back
3. I booked an appt with my personal gyno for next week- what are some tests I should ask for/anything worth mentioning
4. is this for sure CV?! WHY DID IT COME BACK A WEEK LATER and now the douches and paste AND suppository aren’t working :((
