I have been having lower back pains, soreness in my abdomen area and only slight nautiousness.  I do not recall when my last period was, I usually have it after the 20th.  I do know the only time I had unprotected sex was December 6th.  Both my sister's are pregnant and Due January 25th.  I don't want to take the limelight off of them and if I asked my mother she would blurt it out to my sisters who would be annoyed.  I just kind of need someone to talk to and make sure its not all in my head!
