Impending doom...

I think AF is on her way. I usually get gas pains the day before she shows, and I've had them on and off most of today. What's weird is sometime between last night and today glow changed my start date to today. Odd. My cycles are ALWAYS 29 days. Aside from the gas pains, I've had slight nausea, and a lacking appetite. I guess it's fair game. 14DPO today, so we'll see what tomorrow brings. Still holding out hope that yesterday's bfn was just a matter of not enough HCG. Read online that the $ store tests aren't as sensitive as others and only pick up HCG starting at 50?!
