I didn't understand my pharmacist's explanation for the boric acid suppositories?

Good evening, since my vaginal pH is constantly disturbed, especially after my period or after an intercourse, I was prescribed boric acid to be applied intra-vaginally and it is the first time in 5 years that a treatment works. However the effects do not last long and 2-3 days after the treatment is finished, the odors and redness start again. Earlier I went to my pharmacy and the pharmacist told me that it was ok if I didn't take the boric acid for 14 days (that's what it says) and I explained to her that after only one ovule of boric acid I see a huge difference. I was pretty stressed and uncomfortable since it was so crowded so I think I misunderstood, but I think she told me I could put it in quite frequently (if needed) like 2-3 times a week just to maintain some balance.
