Could I be pregnant if my priod is too early

Possibly... sometimes a period that is lighter than normal, does not last as long as normal, and comes a bit off schedule may not be a period at all but early bleeding in pregnancy.

If it appears to be like your normal period, but just a little earlier than normal, odds are it is just an off period... which sometimes happens.

How old are you?

Are your periods regular?

Are you on any form of birth control?

Taking any medications?

Any weight loss or gain recently?

Stress?

I hate to answer questions with questions, however your OP was so vague it's impossible to help you without a little more info.
