No way to know : Unless you are late for your period in which case you can check a pregnancy test. Spotting before you get to when you'd normally have a period - normally day 28-30 of cycle - may not mean anything.

Take a test : If you think you might be pregnant check then check a home pregnancy test. They are cheap, reliable and available at any pharmacy.
