I'm so sorry you're having a hard time. I agree, the 2ww is the worst. I know for a fact in not pregnant and I'm still not able to sleep for more than two hours a night because I just can't shut my brain down
Happens to me at the end of every cycle, my mind racing half the time trying to clutch at any straws hoping I'm pregnant when I know I'm not, the other half just overwhelmed with sadness at another failed attempt.
I know what you mean about being devastated at another bfn, but if it was me, I'd have to test. If i didn't, id spend all day wondering whether it would've been a bfp and it would just torture me. At least with every bfn I get incredibly sad, but more prepared for the arrival of the witch... But that's just me
Just know we're here for you whatever you decide to do, and we'll cheer you if it's a bfp and understand more than anyone else how you're feeling if it's a bfn...
Good luck!!!!
