Is this healthy??

So ever since I stared my period, when I am not on my period I leak this white stuff that looks like cum. It's not. And it seriously smells like dry or old urine. I have no clue what it is because they doctors say That my ovaries and everything inside me is working perfectly and they are healthy. This is really bugging me and I need help to know what it is so I can talk to my doctor about what I possibly it could be.
