I recently moved to my new home town where i only have tile floor both down stairs and upstairs. I was cleaning out ny floors and moving the futon mattress and i fell and the heavy mattress fell on my stomach. I was completely helpless and my son though i was playing around and was laughing .i started crying since i hit the floor pretty bad andmy pelvic bone was already hurting. I was literally stuck with a heavy mattress ontop of me and couldn't move . I guess my tears were a projection of how helpless i really am since my huaband is never around. -.- . I was so scared but my baby is moving fine.
