Domain pointing to old hosting service

Hello.

I’m having a bit of a problem setting up my first Cloudflare account.

I recently changed my website hosting and transfer my domain to it too. In the last days I begun setup of Cloudflare to protect and turn my website faster, but then I came across a problem.

Despite creating an account, changing nameservers on my current hosting and Cloudflare saying that everything is okay and active, it points to my old host IP’s and Cloudflare nameservers.

What can I do to change this?

Thank you!
