When to call the doctor?!

I am officially over 2 weeks late for AF. I have sort of regular, long cycles.. Typically around 36-42 days. Well, today I am on CD 57.. My last AF was May 6th. I was thinking about waiting until July 6th as I would then be 2 months late?? Should I call sooner? I figure with the holiday this weekend I wouldn't be able to get in until then anyways. I haven't tested since about a week+ ago and it was negative. No symptoms really tho I do feel like my boobs are bigger and I feel like I have gained some weight. I've had a ton of EWCM for the last week or so and that's not usual for me.
