17 DPO, CD 32

Becky • Busy SAHM with toddler and newborn!
I know there is a pinned discussion on this, but I couldn't find an answer I was searching for -- is there ANYONE out there who couldn't get a BFP even at 17 DPO? I have been dealing with low back pain, nausea, dull cramping, super smell, uncontrollable mood swings, very fatigued, threw up my coffee 2 mornings in a row...I'm concerned because I'm still getting BFN as of yesterday. AND I had some light bleeding four days in a row at 10 DPO.  Was too short & too light compared to my normal period...and over a week early. Am I at the point to where I should be getting BFP if I am, in fact, pregnant?
