Alright ladies,

I'm a week late today with BFNs. I've got an appointment with the doc tomorrow for blood tests! My cycle is regularly 31 days long but the longest it's ever been was 40 days once (when I was traveling). I'm hoping I'm pregnant and this is like my last pregnancy where I never got a BFP at home and then got one at the docs at 7 weeks.. Nothing has really changed this last cycle to affect it's length (although it's entirely possible it's something besides pregnancy). Any ladies with similar stories?? Did you get BFNs at home only to get positive blood tests? Any late BFPs?? I'm going insane.
