Setting myself up for disappointment??

Hi ladies on the 25th of this month I had my third iui using clomid and gonal f injections and also trigger shot!  Something about this time jus feels different I usually don't get my hopes up at all and sort of talk myself out of even thinking it might work BUT this time I jus have a really good feeling that it will work....I feel so hopeful and calm! Do you guys think I am setting myself up for disappointment or do you think I should go with it and embrace it! We have been TTC baby number one for three years now, diagnosed with unexplained so it's been hard to say the least!!
