I'm so sorry to hear about your friend!!!

The best thing you can possibly do for her is to be her support! I know during my m/c that is exactly what I needed. Even if it was just a simple text message saying "I'm thinking of you, how are you today?"
I know what you mean 100% about the possibility of being pregnant! I'm NOW officially 6 days late (as of Thurs. Oct. 18th) and I kept getting a BFN until my last testing day which was Tuesday. All I can say is wait and test in a few days. I managed to convince myself last night that I'm having a "phantom pregnancy" but, my boobs are extremely sore today, so I'm not too sure about that!
Anyway, sorry to hijack your thread, but like I said, wait a few days and test again. Let's hope you get your
