There is a chance that you are pregnant but very remote.
To get pregnant you have to be ovulating. The average women ovulates about 7-10 days after her period ends. Since your period just ended, the chances are slim that you would have been ovulating.
So a period of 2 to 3 days immediately after or before periods are highly safe.
You have to have egg released from ovary for pregnancy
to take place and if you are not ovulating,from where the egg would come.
