Bad/unhealthy cravings..?

So I wanted to post this to see if anyone else has had this happen with them. I have had very uncommon cravings.. for unedible objects. I have done some research about it and it has came up for an iron deficiency, and I am anemic. But I crave the smell and to chew on a sponge, the smell of detergent to the point where I want to drink it, and when I brush my teeth I love the taste of Colgate toothpaste... lol has anyone else experienced or is experiencing this?
