Hi I’m 33 weeks 3 days pregnant and I’m constantly having the cravings of eating bricks and slate chalk and raw soaked rice, and I had bricks occasionally during my third trimester and little big chunks and I feel restless until I eat a piece & I know I should’nt eat but I cannot control the urge. Will it harm the baby in the womb I’m so afraid I ate bricks 3 to 4 times a little bit big chucks and raw soaked rice too can you help
