Hello ? I'm at 37.5 weeks, my belly has become very soft, it was always tight and firm before, there was no tone on ultrasound. Can you say that this is normal for my due date? Did anyone have something similar? And the pelvic bones became smaller, I couldn't move because of the discrepancy in the pelvis, now I can already turn over from side to side by myself, sometimes it hurts, but not as much.
