Opinions would be appreciated. ..

So I'm now going on 3 days late....no cramping, no spotting, I'm not broken out on my face nor am I craving chocolate or eating the house down, I took a pregnancy test at I guess almost two days late and I got a BFN! I'm going to retest in the 2nd if nothing happens as that would be seven days late but I'm confused as I am NEVER late I feel stings in my lower abdomen and I just "feel" different....how many women have been two or three days late with BFN but turned out to actually be pregnant? Fiancé and I have been TTC for over a year now and I don't want to get my hopes up for nothing but I can't help but to think maybe this is it....I also don't want to jinx it either, what would you do of you were me?
