Pee sticks are cruel. Even though you know that it's early doesn't make seeing one line any easier. I really, really hope you are one of the many people that sees that second line in a day or two. Hang in there, this is the worst part of the wait.
I know that I am new here, but your words of frustration could have come right out of my mouth. I know how badly I feel and it just makes me sick that our experiences and feelings can be so similar. I know comfort is hard to come by right now but I don't think you have done anything wrong or stupid or wasteful and none of this has anything to do with justice.
