Pressure

Ok so this is my second child so I know what the pressure is like but just recently I started getting ALOT of pressure. Like when go to the bathroom or when I'm like squatting down to play on the floor with my son. It literally feels like I'm going to rip open down there. I have get pressure before this but this time it huuuuurts. Like it really feels like it could just rip open and she would fall out. Normal?
