Vaginal Odor Help!?!

Okay I seriously need help serious answers please. Okay so if this makes any sense I work 12 hour shifts a day 5 days a week. I take showers and baths every day. I use vagisil wash everyday. I take feminine vitamins everyday. I use rephresh odor eliminaters about once every week. I drink cranberry juice everyday. I make my boyfriend shower before we have sex. I shave my lady parts and everything. I have tried everything to make my viagina not smell. Tbh I dont smell in the morning but going through out the day after about the 3rd time using the restroom at work. I start to smell a fishy smell down there. I have had bv before and I took antibiotics to get rid of it. I'm at the end with this situation because I'm a very clean person and its embarrassing to smell like that when I have tried everything. I've been dealing with this problem for some time now. Please does anybody know what can help to eliminate odors down there???
