Hello everyone) I've been waking up every morning for the past 3-4 days at 3am, then 5am, sometimes 6am, and then 8am. I walk around the house forcing myself to sleep, feeling like I'm lacking oxygen and weird dreams pop into my head. Could these be signs of an imminent birth or am I just overthinking it ??
