cycle day 42

Ag
Wow! My latest has ever been 37 days and even then I had cramps from day that AF was due! 
No cramps l, no sore breasts and I'm 
1) frustrated as I'm going for <a href="https://glowing.com/glow-fertility-program">IVF</a> blood tests on cycle day 2...that hasn't come (so we can start <a href="https://glowing.com/glow-fertility-program">IVF</a>) 
2) negative pregnancy tests!
Anyone else had this same issue and either been a) pregnant or b) had something happening that wasn't normal?
