I am 30 weeks pregnant and have had no cravings except to eat the burned wood charcoal from the open fire in my living room! I have received very mixed responses to this with some people saying that its a no no and others saying that its actually good for you! Does anyone know whether it is harmful or not when pregnant? I asked my midwife and she just skirted round the issue, probably because, as is usually the case, she didnt have a clue! Any advice is appreciated.
