Hello. Yes. It is always good to know you're not alone.
I have had pains that made me think I would have my period any day.. but it has been happening for a long, long time now.
I have been told I have endo too, but I haven't ever missed a period before.
I didn't think I was stressed either... but I have been waking up every morning hoping for a period. Maybe just thinking/hoping does something to make it late. I have no idea.
I have had 3 blood tests within the last time I could have become pregnant, and none of them have been positive, so I am pretty sure I can say I'm not pregnant.
And thanks for the suggestion on the thyroid, but I checked what all of the tests were checking for and one was thyroid problems, and the results were apparantly normal. So I still don't know.
And I am 20 years old, if that makes a difference.
