Girls, hi everyone. I can't sleep past 4:00 AM. There's not enough air, like something is stuck in my throat. I can't lie down straight, there's not enough air and thoughts like "how will I give birth if I can't lie on my back? I can't breathe! Who has this? And could it affect the baby? Is it possible that gestational diabetes after childbirth affected the child? Because they scare me with hypoxia, large babies and organ hobbies?
