Testing timing and late periods

Kat

Last time I got pregnant, I got my BFP a few days before my AF was due! Now TTC again, I felt the same way I did last time; pinching and pulling on DPO 12, mild cramps and fatigue oh i got sweaty too. I was being patient this time and waited on the second day of missed period. It came out negative. Anyone have different outcomes with testing? Brands, timing etc
