Thanks Sarah_H and butterfly_warrior for getting back to me. I am addicted to testing so I know I am going to go crazy waiting for Sunday to arrive. It is not far, but you know what it is like. Butterfly_warrior: you have given me hope, that you got a BFN a day before your BT.
I just hope it works for all women who want a child so much, I hope to God that it works for women who are struggling and are desperately wanting babies.

Thanks once again for your help.
