Hey there, destiny: welcome to the boards.
It's not likely that your pubic hair is the issue when it comes to the itchiness if it hasn't been an issue before, and we can be sure it isn't the cause of changes to discharge, which start inside the vagina. It might well be that you're going to need a healthcare visit to find out exactly what's going on here and get any needed treatment, but I can probably help you narrow the possibilities first, if you like.
That discharge: is it more thin or more thick? Is it more white or more grey or greenish? Is it clumpy? Does it have a smell that's different from what you're used to with discharge? If so, what's that smell like?
Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has. - Margaret Mead
