The last time I was with my boyfriend was December 26/2011, after that we were not together. Soon enough I find out I am pregnant, the doctor told me my due date is october13/2012 as of today Sunday April 8 I am exactly 13 weeks and one day, how is this possible? Shouldn't I be 16 weeks? My first day of my last month period was December 17/2011

Hi Scorpiomomma,

How did your doctor come by the due date of October 13? Did you have an ultrasound done?

Yeah

I agree with you, the dates are off. What did your doctor say when you told him that the last time you had sex was the end of December? Have you had a second ultrasound? I would bring it up with your doctor next time you go in and maybe see about having another scan done. Ultrasound is not an exact science, but early on it is usually fairly close. Did your doctor do the ultrasound or did a technician do it?
