Fustrating to say the least!

3 days late and negative hcg tests ( the one step internet ones that are suppossed to be 10 sensitive) no cramps dizzy and feeling so fustrated. I am never normally late so i now understand how fustrating it is for women who have been through this waiting game. Surely by now i should have had a positive test? Af will proberly get me today or tomorrow. My bbt has dropped again slightly today although still high it seems to slowly be going down.
