Bad smell

I feel like ever since I had my son (he’s our first and only at the moment), I have had a bad odor down there like all day long no matter what I do. And he was an emergency c section if that matters. He’s 16 months old now.

Is this normal? Anyone experience similar and have any suggestions? 🙈 I’ve never dealt with this before having him but I feel like 16 months means this is a new normal. My husband says he doesn’t notice but maybe he’s being polite. Also, I’ve been on a clean eating diet for a few months now and drinking a gallon of water a day for weight loss purposes and still no change or improvement with the smell. 😭
