Am I pregnant or what?!?!?!?!?!????

[cheytd]

So I've posted here a few times a couple of weeks ago about my story and everything that has happened this month, at the time when my period was a week and a half late. Everyone who responded said I'm most likely not pregnant and it is probably stress that's making my period late.
It has now been 20 days since my missed period. And I am now in a 51 day cycle. I've been keeping track of all my periods for the past two years. And even having weird periods because if going through different bc's (which I now haven't been on since June 2012), and having all sorts of wacky cycles, the past 6 months they've been pretty consistent. And in spite of those weird cycles this is the longest one I've had by over 10 days.
Everyone including myself seems certain that it isn't likely that I'm pregnant.
So I guess I'm wondering if stress alone, if minor enough to be taking no physical effects on my body, if its possible that its making me miss an entire month. My next period is supposed to start march 6th. Though that's only a week away and my usual cramps and irritability isn't here yet, and it usually comes one week ahead if time on the dot. I can't "feel" it coming. But last week I took another hpt and its still negative. I don't know if I should be worried.
I do plan on making a dr appt for next week or so, but I can't get this off my mind.
Am I pregnant of what?!?!

Try to get a blood test.

And to the comment above she said she is 20 days late and on cycle day 51.

Please go to your doctor...

If you're 51 days late for your period and you've taken tests that keep coming back negative then you are most likely not pregnant. I would recommed seeing your Dr for a blood test and maybe some other testing to find out why your period is so late.
