I just understand girls who go until the very last one?? I'm at week 40 and I'm just falling apart. And it's not even bearable pain. It's unbearable... The tailbone feels like it's splitting apart and any movement, especially getting out of bed is painful... how do you survive childbirth if you don't have the strength right now? I apologize in advance for whining.
