My heartstrings pulled when I read your message, I just wanted to send you a message of encouragment and comfort.
Usually home test kits take 2 weeks to be accurate unless they are the very expensive ones (the 4 day EPT for example). The cheap tests have been negative at 2 weeks or more even when you really are pregnant, with my son it was almost a month before it tested correctly---when I knew in my heart I was at 2 weeks but it said negative.
I hope this is helpful for you, and may you have a safe, healthy pregnancy! :) Caitlin Lorraine
