If you got your January period, you are not pregnant. But since you are clearly wanting to BE pregnant, you presumably have had sex i January as well, yes? So if you missed your February period, you could be pregnant.

There is no one size fits all. You may have a period the entire pregnancy or have your next period but skip the others. Normally you would have your next period but it would be very light and spotty.
