: over thinking it :
Call whenever you want. An initial call want come off as needy. If/when you start dating if you start tracking/calling/texting her every hour of the day... that is needy/insecure.
BTW saying we are 'just meeting up for coffee' is really a way of being able to bail if the moment she met you, she wasn't somewhat interested. Since you guys hung out for awhile I wouldn't sweat it.
