Am I talking fast enough to sound fluent?
Actually, you might sound more fluent if you slow down. If you try to talk fast you’ll make more mistakes, and it’ll be difficult to understand you.
How fast native speakers talk varies. Americans use “uh” “um” and “like” or even “let me think” while we are thinking; use things like that a lot if you want. (On a test like ielts or toefl using things like “um” or “uh” is a bad idea, but otherwise it’s normal.)
Talk at a comfortable speed for you, and (reasonable) Americans will be able to easily understand you, will enjoy talking to you, and will quickly be impressed with how advanced your English is.
