I have had issues for a few years with leaking urine and wetting myself a bit when I sneeze/cough/fart but today I needed the loo (not very badly) and as I was standing undoing my trousers it suddenly started happening and I couldn't stop it. Thankfully I was at home and I just had to change my trousers and mop the floor but I felt really tearful :( What could this be? I do have endometriosis and currently have a large endometrioma (11cm) which is being watched but that has been there about 2 years.
