Oh dear, please don't eat chalk or mitti at all. I had similar cravings during my pregnancy and my doctor told me it's because of low calcium. Please talk to your gynac and get your blood checked.
Honestly, eating chalk is a big no as it can have harmful chemicals. It usually means you are deficient in iron or calcium. Just call your doctor's clinic and ask for a quick blood test instead of risking it.
Please don't eat this, it can harm your health and the baby too. Such cravings are common but you need proper vitamins. Discuss this with your doctor during your next follow-up and get your levels checked regularly.
I literally had this exact urge to eat multani mitti during my last trimester! But my gynac strictly warned me against it and gave me calcium tablets. Please consult your doctor before eating anything like this.
Oh sweetie, please do not eat chalk or mitti, it is not safe for the baby. These cravings usually mean your body needs some essential nutrients. Please check with your doctor immediately to stay safe.
