I need help

I am 24 years old and in great health. My husband and i have been ttc for 3.5 years now. We have been diagnosed as unexplained. We have done 6 cycles of AI with chlomid and 2 cycles with follistim and AI. I have also tried hypnosis, accupuncture, vitimens anything I hear about I have tried. I am having a very hard time dealing with this. My husband is supportive. I did have friends that were supportive. Every friend I have is pregnant and I cant be around them it is way to painful. Can anyone give some advice. Also maybe a method to conceive I have not tried.
