I am two weeks later for my period and took a test last. Week and it said negative could I still be pregnant and what should I do?

Retake test. There are lots of reasons a persons period can be late. If there is a chance you could be pregnant then you should repeat a home pregnancy test. If it is negative then waiting a few weeks to see if it returns is reasonable. If it does not then it is time to visit your friendly obgyn doctor.
