Funny smell down there !

So I just finished ovulating and I’ve noticed this weird smell coming from my vag. Lots of discharge and I just thought maybe I’m overreacting

It doesn’t itch and my discharge is normal.

My discharge smells normal when you smell it but when I have clothes on there’s just this fishy smell

I don’t know if I’m paranoid or what

I’ve been taking cranberry supplements religiously

What could be the cause of this ?
