I'm 34 weeks 4 days pregnant and for the last few weeks I've had the strong urge to eat a stick of chalk. I had the craving with my last pregnancy and didn't cave in but this time it's stronger than ever. I think it's the crunchy crumbly texture I need. I'm watching youtube videos of people eating natural chalk pieces and it makes my mouth water. What would be the worst that could happen if I ate some chalk? The only thing stopping me is the fear of harming my baby. But I am finding it so hard to not just cram some of my kid's chalk into my mouth.
