my lower pelvic/tummy feels like it is being ripped apart whenever i try to sit, walk,lay down, roll over pretty much anytime i move. When i can manage to lay down i feel like i am going to vomit, i keep getting dizzy and im sweating what could be the cause of all this pain? It also feels like she is standing on my water and that it could burst the feeling/pressure only last a few mins at a time is this normal?
