6 days late

Elokin • Ttc that precious little girl after having 2 teen sons
I have normal cycles that range from 26-28 days, I am now on cycle day 33 about 6 days late, no sign of af. Took several hpt and all negative. Cervix is so high I can't reach it. Has anyone in this group had anything like this and ended up pregnant? Or is it just my cycle playing a cruel joke on me?
