Pregnant?

Alicia
I am new to this application. I stopped taking my birth control pills on Sept 28. My hubby and I had sex during my best days to conceive. My period was due yesterday and I still have not gotten it nor have had any signs of getting it. I took a pregnancy test this morning and it turned up negative. How many of you had to wait for at least a week or so after missed period to show a positive test? I believe I am pregnant, I have had sore breasts, nausea, fatigued... So I do have symptoms. I have already had 2 kids but I don't remember how long it took to get a positive after missing my period.
