My Last menstrual Period 12/20/2007 ans I had sex on the 1/07/2008 and since then I have been having sex. As of today the 2/1/2008 I haven't seem my period.

This has happened before last year I didn't have my period in Nov and I went to see my doc and I wasn't pregnant and in Dec my period came.

What could it be??

Stress or diet are the first thoughts... If you are concerned, see your DR.

Weight, stress, uneven cycle, diet.
Are you trying to get pregnant ?
