So embarrassing! ๐Ÿ˜๐Ÿ˜

I work at a daycare with preschool aged kids. One of the kids was sitting down underneath my chair and she moves up closer to in between my legs then goes "it stinks down here" of course I tried to play it off as something else. ๐Ÿ™„ย 
Then later that day another kid mentioned it..ย 
I just got off my period and I guess had some odor in the down stairs area..ย 
Does anybody have any advice on how to help it? I worried about it all day, went straight home and showered!!ย 
I took a shower right before I went to work and I washed down there decently well (well at least I thought)ย
