Girls, please tell me ? What's going on? I've been wanting to eat "something" for a week now, but I can't figure it out. I just can't anymore. If it's a vitamin deficiency, fruits, vegetables, I eat them every day. A salad with greens. Green juice from spinach and kale, and even sprouts. And literally three days ago, I wanted to eat something like powder in spoonfuls ?. And I just can't. Maybe clay or talc to try buying? Has anyone had this? Right now 30 weeks before that, I haven't had any taste preference for anything. I ate as usual.
