Hi again, girls I'm now 36 weeks and 4 days — well, according to the app I downloaded on my phone; the doctor counted that I'm 35 weeks and 4 days. Is there any way to speed up labor? I can't take it anymore, my whole body and ribs hurt, I walk like a penguin; with my first child this never happened at all. I want to give birth at 37–38 weeks already — are there any methods?
