Can you over use boric acid for yeast infection

I’m using the pills instead of suppositories, I believe you do like 7 days for yeast infection and like 2 weeks for bv but I lost track at how many days I’m at , but I do want to use the whole bath just to make sure all my yeast is completely gone . (I had it ever since I was pregnant 4 months ago until I started taking these which was last week) so that’s a pretty long time to have a yeast infection and just wanna make sure it’s ALL gone . Is it possible I’m able to do it for 2 weeks or is that over doing it
