I need help urgently! After giving birth, I have such a problem... started involuntarily leaking urine... especially when coughing or sneezing. I went to a gynecologist, she says that I have urinary incontinence, offered some exercises, candles., nothing helps. I've been suffering for over a year now, I don't know what to do??
