Can oral probiotics and lactic acid gel cause CV?

If you had CV, was it caused by too many vaginal probiotics? Or did you take oral probiotics that led to it?

Ive never taken vaginal probiotics. I take 1x optibac for women intimate flora, and 1x seluni every day orally. Also in the last month I took relactagel (lactic acid) vaginally for 5 out of 30 days.

My symptoms (soreness, irritation, watery and white discharge) fit the description of cv.

I am now really scared I've caused CV. I haven't taken a microbiome test cos I'm in the uk and I'm scared of spending all this money only for a GP to tell me they aren't interested in my result.
