So I’m not pregnant..but we are currently ttc. My question is, has anyone ever had very strange cravings before? Like not edible cravings... the last week or so I’ve been craving like rocks... idk why😭 this sounds so embarrassing to even bring up but like I’ve been craving an earthy gritty taste lastly and I know I’d get that relief from rocks and or sand... I haven’t actually eaten any of these things but I’ve been craving it...is there something I’m lacking for me to want to eat these kinds of things?
