Please describe your discharge. Is there an odor/color? Have you resumed intercourse/any problems? Any change in your bowel movements? Any medical problems or surgeries?
Your urine leakage is just stress incontinence. If these symptoms are occasional, then you can hold off on treatment. If frequent or you find you at times smell like urine, talk with your doctor about bladder testing and treatment options. There's another simple surgery your doctor can perform for stress incontinence if necessary. Yellow isn't very concerning, but brown could be old blood (or stool as above). Again most cases are benign and treatable so try not to worry. Not worrying may be difficult for you until you get answers, which hopefully you'll receive when you visit your physician. Make sure you write down your questions so that all of them are answered so that you don't go home, realize something and start worrying all over again. I hope this helps.
