You are a new runner. Try to go out and NOT worry about timing everything you do. Just go run and build your base. Everything else will come.
I NEVER clock a mile when I train. Now, I am not lightning fast, but I can place in my age group (30-34) in most 5K's (about 19:45 usually) and 10K's (PR 41:50). The most important thing right now is building your base. After a while you can start doing the other things like speedwork and learning pace(s).
Just go out and enjoy yourself.
