Advice please

Hey ladies. Just would like some advice. I noticed lately at the end of the day my vagina doesn't smell as fresh anymore. Not a fishy odor or anything but like a strong sweat smell. Never had this issue before. I've been to the obgyn had tests and everything done. Everything came back negative and she didn't understand what I was tryin to say was wrong. Any advice on how I can stay fresh all day long. I use baby wipes when going to the bathroom and I don't feel like I'm sweating but somehow at night when I take my clothes off there's a not so pleasant odor. 😢😔
