Where your pelvic floor is
The pelvic floor is a layer of muscles that runs from your pubic bone at the front of your body to your lower spine at the back. Think of these muscles as a hammock or trampoline which support and hold your pelvic organs in place.
Your pelvic organs include your uterus or womb, vagina, bowel and bladder. The muscles should react automatically when you cough or sneeze by squeezing and stopping you from leaking urine.
