Keeping my hopes up but know I'll be strongly disappointed again

L
AF supposed to be here tomorrow I've been cramping for 26 days now(which is unusual for me) and been having sex just about everyday in and out my fertile window. This happens everytime I get excited just to get disappointed constantly I try not to get discouraged but how does the first time around happens so quickly without even really trying but this time it's like a never going to happen thing.
