Does Clindamycin work for BV?

I’m on day three of Clindamycin pills for BV and it hasn’t gotten better :( there’s no smell now but still pain when I pee , cramping discharge etc. could this pain just be from the area still being inflamed but maybe the infection is going away? It just hurts and this is so frustrating. I’m taking probiotics , using boric acid at night , nothing is working. Does the gel work better?? Any advice would be much appreciated. No mean comments thanks.
