It would be really helpful is someone can give me a answer tanks.

Do you mean the first or third of Jan, ( not 31st)

If you have the period only for a day or two, this could be pregnancy, Normally if it is a regular period, no you are not pregnant.

Normally there are no other signs of being pregnant, till you miss your first period.

You may have to wait and see if you have a regular period
* it is not uncommon to at times be early a week or so, or even late a week or two.
