(( VaginaPagina ))

I get this sometimes a few days before my period starts properly and I'm not a smoker. Sometimes I put my cup in thinking my period is about to start and I get this instead, it's chocolate brown and kind of a sludge-like consistency (gross, I know). It doesn't happen all the time, just occasionally. Then the last day of my period I get the same consistency, a little bit redder of a color.

I really don't think it has anything to do with tar or smoking, unless someone's been blowing cigarette smoke into your vagina.
