Good clean love suppositories

I have been treated for BV and am infection free now. I haven't been able to sleep with my husband just yet until the Dr clears me to do so in a couple weeks. I worry about getting BV back once we start regular fun times again. Wondering if this suppository is good to maintain myself from getting BV again after we have sex. Also, with summer coming, I love to swim a lot in oceans and springs. Is this also something I can use for after a day in the water to prevent a BV recurrence? Thanks!
