So I'm 5 days late with all negative tests, no signs of my period starting anytime soon. I've had sore breasts and that was the only symptom and now I'm 5 days late with no sign of AF coming . I was wondering if I'm pregnant and how long it could possibly take for me to show up positive on a test? Anyone else have this issue my period is never ever late I'm always a solid 28 day cycle. My last period was March 12th.
