I know the feeling @MissBell I'm due to start my 2nd cycle after I had nothing fertilise from the 1st collection. Total devastation and completely unexpected.
I had my daughter 5 years ago and conceived naturally. Been trying for the last 4 years and developed PCOS and hyperthyroid along the way. Somehow I fell preg naturally just before I was to start my first cycle. I found out at 6 weeks and was blown away but there was no heart beat. Serious give me a break!! So I had a D&C waited a few months and tried the IVF. Embryologist was shocked that nothing fertilised because eggs and sperm looked great and I had just had a recent pregnancy.
Onwards and upwards, I'm waiting for AF hopefully tomorrow so I can start my next cycle any day now.
Good luck to all of you!!
