26 weeks pregnant. Iron levels are fine. Last week I had a real craving for the smell of talcum powder, found an old tub and couldn't stop sniffing/smelling it. Which has now moved on to licking it off my hand 
I really really want to eat it. This is weird no? Last pregnancy I had the same thing but with washing powder (did not eat it obviously) and it went as soon as the baby arrived.
Yeah so...,please tell me I'm not the only one
