AF where are you??

I am on cycle day 35. Where is AF?? I am NOT pregnant, already checked! I am so crampy, but it just isn't showing up. I want to keep moving, not waiting. Ughh! We have plans to go out of town for the upcoming weekend (3 day weekend), so I am hoping that I don't need the day 3 bloodwork on one of those days. I could probably find a place to draw it where I will be, but I much rather do it at my local clinic that ships to CCRM all of the time, they know whole routine so I won't have to worry about it being done incorrectly. Please show up ASAP AF!!!
