Hi Rebecca, There are reasons forthis and this can be a change of pH in the vagina, caused from fluctuating hormones, can also contribute to a vaginal odor. Also some women start to leak small amounts of urine in menopasue. Making sure that you change you have cotton underwear can really help with this and help with the hot flushes in soaking up sweat which can lead t smells. If you think you have continuing noticable smell its good to check with your GP as many women have more frequent UTI , too.
