Okay im confused!!

Rachel

Perusal I'm confused. I just came from my 1ST OB Appointment and by the sonogram I'm 5 weeks 1 day today... But, my last period was December 9th. I'm not pregnant in my tubes. The saw a gestational sac in the right place. I guess my question how do I determine the due date?

Remember how I said that my numbers weren't climbing high enough, that's why. I was earlier then I thought, silly me.

But someone please explain this to me.
