Negative results?

Samantha
Has anyone else gotten a negative after their bfp? I'm a little worried. No period, sore beasts, cramping, bloating... I'm usually super regular, got a bfp the first missed day (Friday, was supposed to start Thursday). Dr appointment Tuesday to be sure but really hoping I'm really preggers, hubby is stoked about it, I think we'd both be pretty depressed if it came out to be a false positive.
