Vagina taste and smell after hysterectomy

I’ve never had any bad smell or taste before my total hysterectomy. I only have ovaries left. I was told I taste sweet. Now I smell like fish and sour taste at times. I’ve tried so many different probiotics and chlorophyl liquid to improve the smell and taste. Oral sex is extremely important to my husband and myself. I’ve been checked and have zero infections to cause these issues. What do you recommend I take? I’m desperate to be back to how I was before my hysterectomy. I appreciate your answer 🙏
