Okay . . . I'm trying to be supportive, comforting and give you hope right now, which is difficult because I'm currently feeling the exact same way!
Let's try this . . . tons of people don't have any symptoms, which is how people can go a few weeks before noticing they are pregnant. And we've both had cys where we feel tons of symptoms, and we aren't pg, so maybe no symptoms is a good sign. I'm feeling better this cy than in any other cy (of course I still can't shake the feeling that isn't a good sign).
Your temp isn't going to tell you much because of your disrupted sleep, so don't pay attention to it! And 8 DPO might still be too early for symptoms . . . we could just be implanting today!
I'm not sure I helped any . . . but know you aren't alone in this feeling. All of us in the 2ww are going through the same things. I'm hoping we are both pregnant . . . and if not, on to cy #3 for me! In the scheme of things, we haven't been trying very long . . . not that it helps me with my patience. When I want something, I want it NOW, and it is frustrating when it doesn't happen on my time frame. Just wait 'til you see what a wreck I'll be tomorrow if I cave in and test . . . knowing it is too early and knowing i'll get a bfn, i'll still be pretty devastated.
So . . . I'll just keep waiting with you.
