	I am confused about the due date for pregnancy. My LMP date was around sept 23 2008, my 2 early ultrasound dates put gestational age to 30 sept 2008, and my due date is july 07 2009. When would i have conceived? And it is possible to become pregnant a day or 2 before a period starts even though it was protected sex, or is that impossible?

	Answer by Dr Vinod, MBBS,FcGP  (doctor) on Wed 27, May 2009 06:14pm: Dear jacquelimeklaire, Normally Obstetricians calculate LMP from the 1st day of your last menstrual period. The exact age of the foetus though would be from the ovulation & fertilization day which is 14 days after the 1st day of last menstrual period. So this is the common reason in discrepancy and patient’s confusing. You can always determine it by ultrasound and abdominal positions and many other methods. Take care!
