Could this mean something?

Kathy

So, before I got pregnant, I could always smell my period as far as a week before it would show up (weird, I know). I'm currently 33+2, and have been smelling it again on and off when I use the bathroom. I always check to make sure there isn't any blood, and there never is. I haven't been having any cramping (other than from gas or constipation), and theres been no other signs of labour or anything like that. But I'm just wondering if it could mean anything? I'm not stressing over it or anything, just genuinely curious. Has anyone else had this kinda thing happen?
