Hi Lee,
IVF is an emtional rollercoaster as you well know and it is very hard to stay positive but it does work eventually. After 4 years of TTC which included 7 IVF cycles (5 full cycles and 2 FETs) I finally fell pregnant with my DS. Then again last year after 3 FETs we were blessed with our DD. It took 7 years in total but it did work.
I was lucky to have a few friends who were going through IVF or who had been through it who gave me support and every one of them eventually had a baby, the time it took to achieve it just varied.
Good luck with your next cycle, I wish you the best!
Monica
