well it's not over till AF shows. some people dont get a bfp until after their AF is due. what type of test did you use. with my first pregnancy i did not come up as positive until after my period when i used a dollar tree test but i came up positive on a FRER.
I know how you feel...I have taken 3 HPT since Friday and all BFN...I'm still trying to think positive but getting very discouraged myself. GL!!! I'm due Th or Fri.
