Hi all… feeling a bit desperate. Been trying to conceive for over 2 yrs…I have just done 4 cycles of TI, with Letrozole, trigger and Cyclogest. 12 days post trigger and BFN. Really thought this month would work. Haven’t had one BFP for 2 years. Start IVF next week when AF arrives. Done all tests and nothing ‘wrong’ just unexplained. I am losing hope and feel so depressed. Any stories of success of people in similar situations?
