you start counting your weeks by the FIRSt day of your last period.. and pregnancy weeks can go up to 42... just depends when your baby decides to come out =) and your due date going back 42 weeks is july 2cond.2009 was your first day of your last period, or you could just say your first week of pregnancy.
