Emotional today

AF is a day late and this time I ACTUALLY waited out the TWW before testing. Didn't make it any easier this morning when I saw that bfn. Guess i ovulated a little later than last month so AF should be here any day. I am so upset this time. We did EVERYTHING "right" on the right days. Why am I not pregnant. I have been crying and mad all day. Sorry for the rant. I just am so done with this.
