Really Want To Eat Dirt And Rocks...

Hi I'm 30 years old, my child is one years old, my pica started when I was pregnant with her, and it still continues. I started craving dirt like sand and mud and I also craved pine sol too. It is getting much worse, exspecially when it rains the smell of the wet earth makes my mouth water, I just want to grab the mud by fistfuls and shove it in my mouth..my husband thinks this is very strange. Im very embarassed by this. I have yet to have eaten any mud or dirt, right now Im at the stage where exspecially after it rains I have to be outside smelling the air, and playing in puddles while fantisizing about eating the mud in them. Im happy to have found others in my same situation but Im not sure I want to fix this problem because I have never enjoyed the outdoors as much as I do now, and the smells are so satisfying to me that I dont want this to go away but I fighting with myself to not eat it..
