I had my first period Jan. 13, 2010, and that is almost 2 months ago! I'm new at this and don't know if missing your period for 58 days(so far that's how long I haven't had it!) is normaly?

You might not have regular periods for the first year or two. It could also be that you won't HAVE another period for a year or more.

The body is a complex thing, and puberty doesn't always happen in a straight line.

I'm 12 and I got my period on 23 June 2010. Then I got it again on 17 July.
Don't worry, my friend stayed for about 4 month without getting her 2nd period.
It's all right ;)

It's perfectly normal to be irregular for a while. Sometimes it takes a couple years to straighten out.

Be patient.
