Holiday bfn

Based on my lh tests and temping, today I was scheduled to either start my period or have a positive test. I am 14 dpo on thanksgiving, I spent all week thinking this how amazing it would be to have a positive test today... I thought I could announce on christmas! Fate decided today wasn't the day and I tested negative. No period yet but, I'm sure it's going to be here soon. Can't help but feel like a failure, and I'm incredibly dissapointed now. After trying for 3 cycles with no luck I could really use something to give me hope for the future at this point.
