41 days since my last period...pregnant?

Ok so my last period was April 17, 2015...my cycle is usually 32 days long .. I am now at 41 days still without any spotting.. No discharge.. No period... I have been having a sharp shooting pain in my uterus.. N today I noticed slight cramping... But still nothing... I took a pregnancy test today n 4 prior since last week n negative on all... Am I past the point of still maybe I'm pregnant or should I take one on Sunday if I still haven't gotten my period?
