Girls, how many of you gave birth after your belly dropped? I'm currently 37 weeks and 3 days pregnant, my belly dropped about a week ago. My due date is January 22nd. Two weeks ago I was admitted to the hospital with stomach problems, in the pathology department, already feeling good today, asked when I would be discharged, they replied: "Why discharge you if you're going to give birth soon?" Besides the dropped belly, there are no other signs, on what basis did they even think it's soon? ?‍♀️
