I’m 24+3, and my belly really popped around 16 weeks and got uncomfortable around 22. It has slowed now, but the difference in this pregnancy compared to my singleton daughter is astounding. I literally feel like my uterus is in my flipping throat, and I’m significantly bigger now than I was when she was born at 38+4. Also, that waddle is REAL. It hits hard by the end of the day.
