So looong

The app says me EDD is Aug 27th. The problem is I can't get in to see my obgyn until January 21st ( the receptionist was trying to put me out into February). I'm just so concerned as my pregnancy test line never got as dark as the control line. the first one was faint but the ones after were darker ( still nowhere near the control line) ontop of having some cramping I'm just so worried... After the year we've had I haven't said anything to husband until I can get confirmation that the little peanut is fine. Anybody else having to wait longer to see the doctor?
