What could be a reason for increased discharge?

Hey y'all! I recently got Nexplanon (after switching to another combo pill within like a month long period) and I've noticed I have some increased discharge?

It's just watery/clear mostly. No smell. No weird coloring. It's just more than I'm used to. It's not enough to wear a panty liner or anything but it's definitely there.

What could cause this? I'm 18.
