Help?!?

Jenna

So AF is late by 5 days! I've always had a very regular cycle, and it's never been this late before. I took two pregnancy tests yesterday and they both turned out negative. I know there are many factors that can cause a late cycle such as stress and what not, but that doesn't seem to be affecting me to the point where it would make it late. What could it be?? Should I take another pregnancy test??
