Hi,
I usually have my period for about five or six days; this month I've had it for eight already and the cycle is very strange. The past three days my discharge has been "chunky" and it smells fishy and somewhat of rotting flesh. It's also itchy down there.
I was fine before my period; my SO even (I'm sorry, but I need to give all the info) said that I tasted and smelled fine two days before I got my period.
Any idea what's going on?
One other thing. I use a Diva Cup and for this cycle it was the first month I kept it in the full time. I also absent-mindedly washed it with a scented soap. Maybe there's something there?

Thank you.

I am of a normal size and weight and pretty active.
