8 days late, four negative pregnancy test and a 41 day cycle??!?

Cassandra

Hi guys,

Okay we’re going make this a long story short. So, I’m late eight days to exact. However, I constantly feel the lower abdomen cramps as if my period was beginning but, no blood! I’ve taken four tests within a few hours of each other all negative. So, if I’m not pregnant why am I late? Has anyone ever dealt with this before??? My period has NEVER been late it’s usually like clock work. Please help somebody
