Too Much Amniotic Fluid

Ch
Anyone ever heard of someone having too much amniotic fluid? I've heard of low fluid but never too much. That explains why I literally feel like I'm going to pop every time I sit down. It's so uncomfortable. The added pressure could cause my water breaking and premature labor.. but at 35 weeks (Monday), baby boy would be okay if that happened. I'd be so relieved.. I feel guilty saying that but it's so true.
