I hate the hope of the TWW

I had an IUI scheduled a couple weeks ago and they cancelled it because my follicles weren’t large enough. But the letrozole pushed my cycle back. Typically it’s 28-29 days and I ovulate around day 17. This month I didn’t ovulate until day 21 and I’m on CD 30 now. I know deep down that I’m going to get my period soon. Tested this morning and it was negative. But somehow there is still that little part of me that is hopeful while knowing I’ll be heart broken once again. 😫
