Craving Chalk....

Jade • Amalia Aya Durand.... 18.08.19 💕😍💕

Any idea what this is? Or why it's happening?

Im 24 weeks and It's been a week and it's getting worse, don't see my midwife for another week but the idea of waiting isn't possible.

I'm not even sure how I know it's chalk I want but it's definately chalk I'm craving.
