Hello everyone! I'm 38 weeks pregnant...but I haven't been sleeping well at night, and I feel nauseous in the morning. I still feel nauseous now, and I don't want anything to eat. Yesterday, I only ate potatoes like everything else, and I thought I might have gotten food poisoning, but I feel bad. I don't want an ambulance, but what will they say? Why is this happening?(((
