IUI with positive BV

I have a medicated IUI scheduled for Monday morning and just got back a positive BV test. I will be beginning treatment tonight (clindamycin) but it will only be 3-days of medicine prior to the IUI. I also will be using the medication the night before the IUI at 8am, which I feel like could hinder the success? I don't see much online about this, but looks like if it was IVF they'd be delaying/cancelling the cycle.

Anyone experience this before? This will be my second IUI (got BV shortly after my first last cycle and have already completed one round of Metrogel with no success). I'm feeling torn if I should cancel or if this will hurt the chances of success. I already went through the letrozole loonies so it feels disappointing to cancel. This has been so overwhelming and my doctor seems very nonchalant about it.
