text: my period is 9 days late i took a p test it was a no does that mean i am pregnant?   no.  i think you are more likely not pregnant than pregnant.  many things can affect your period, such as stress, dieting, or a lot of exercise.  it may just be late.  of course, you could still be pregnant, so do another pregnancy test in a week or so.  a doctor may help calm your nerves , make sure everything is all right, and help you get birth control if you would like it.  take care.
