How do you deal with a BFN (over and over again)?

Aggie • Ttc #1 for 2 yrs. 4 failed iuis so far. Going for IVF
Have been ttc for two years, after second <a href="https://glowing.com/glow-fertility-program">Iui</a> just got negative pregnancy results today.  I guess we will go for round 3 next month and maybe consider <a href="https://glowing.com/glow-fertility-program">IVF</a> after that, but in the meantime it gets more and more frustrating each month.  Any coping tips or tricks?
