vagina smell suddenly changed— should i be worried?

basically the title. my vagina has never been odorless, but it doesnt commonly have a bad odor either. i dont think vaginas are meant to be odorless anyways. i have got a bad odor only once, and i quickly was able to find out the cause which was a new bodywash i was using and after i stopped using it the smell returned completely to normal.

now, recently ive noticed my area down there has changed in scent overall. before, it used to have a slight metallic smell with a slightly sour smell. nothing bad, like yoghurt that was kept in an aluminum can for a lack of a better way to explain lol. but for a while now, it smells very nutty? ive never heard someone say their vagina smells nutty. it doesnt smell bad at all. something like the smell of freshly ground almonds and milk. the smell is definitely stronger than before, but again, not unpleasant. its important to say i use no scented products down there, and the smell is definitely from that region, not any other place.

so, should i be worried about this? i feel embarassed because sometimes when im only wearing underwear and i sit cross-legged, i can actually smell that scent. its not a bad scent at all, if i had smelled this prior to this incident i wouldnt even think its the smell coming from a body part but rather maybe the smell of a warm drink or something similar. but im wondering if its abnormal or nothing to worry about. its a very distinctively nutty scent and ive never heard anyone say they smelled "nutty" down there, its also a sudden change, which are all red flags to me
