Fishy Odor 🐠

I keep having this fishy odor. I went to get tested, no STD, I brought up that fact that it could be BV, no sign except clear discharge(which is normal). & I’m not having sex and haven’t since I got tested last month. I decided I would try boric acid pills, from love wellness. This first day it worked, took it the next day, fine but I missed lastnight and I was back with this odor again. I only use dove sensitive soap. I honestly don’t know what’s wrong.
