Such a freakin' skeptic now.....

This month I've been tracking cm every single day, logging in glow religiously, etc.... I've kept track of every little twinge and symptom that seems different from the norm. Today I checked cm (9dpo) and saw a very light streak of blood, and instead of getting excited I just shrugged it off as early AF. I think ttc has made me so skeptical that what I once would've been excited about, now I'm just expecting the worst. This could very well be IB but bc of all of the let down in previous months I'm afraid to be excited. Anyone else feel this way?
