She and her scents

I recently went out with a women I really liked! In a short time, we realized from the story that we have common interests and that we can function well. On the second meeting, we cuddled... However, not everything is ideal, I smelled unpleasant smells when she gets comfortable, which bothers me. I wonder if this is the reason for bad hygiene or if it could be a hormonal disorder or something similar. I'm going to talk to her, but first I'd like to know more about it so I don't hurt her.
Otherwise, the woman is completely ok, sociable, communicative, cultured... She does not give the impression of a person who does not take care of herself.
