I was suppose to start my menstural cycle on November 13,2011 I did not start bleeding till November 21,2011 am I pregnant?

Probably not, but you could try a pregnancy test and see what results you get. It may just be your period is off this month. If you are a teen, it can be normal to have irregular cycles now and then.

You won't have a period if you are pregnant, but you may have some bleeding. Usually it is different from a normal period... shorter, less flow. At times, some women will believe they are having their period and still be pregnant.

A quick test will let you know. Be sure to follow the directions carefully. If negative, see what happens with your period next month.
