anyone else have this problem!!??

Laura • 1 MC at 6wks & 1 baby angel taken too soon 22wks, Oakley had the birth defect of spina bifida. Theodore due 11/10/2017
My little man is sat very low. 
Every time he kick or moves it feels like my waters are about to go. 
It's not a comfortable feeling. I'm worried he will come too early with how low he is sat. 
Has anyone else been or going through this? (26weeks)
