Oh Carla! Hang in there hun! This DOES NOT mean that you are not Pg. It is probably too early just yet, so keep your chin up ok. I have read many accts of people testing negative right up to and including the day of their BT, only to then find that it's a nice BFP for them! I work with someone who has 2 kids and 1 on the way, and she never gets a BFP when POAS until closer to the end of her first trimester??? Wierd, but it does happen.
Please cheer up! I nice surprise could still be waiting for you.
I'll be here if you need to chat or vent ok.
