I've been getting yellow slimy discharge. It's not all the time and it doesnt itch or smell. The disharge is usually white but now and again it's yellow. like, light yellow. Is it normal?

Its quite normal, I had a fair bit with both of my pregnancies. As long as its not foul smelling or itchy down there, you're probably fine. If you're worried though, you could always bring it up with you're MW at your next appointment.
