Baby on the way

Yesterday I attended a soon to be new parent class for two hours (required by Tricare before they will assign you to an OB), then spent an hour at the lab and another hour at the pharmacy and about 30 mins at the admissions. I was given an attentive due date of December 31, 2010. As of today I am 8 weeks and 5 days. It doesn't make any sense to me cause it's been 2 months since my last period and on my birthday it will be exactly two months since Sean got home. So on my count it's been 9 weeks and 4 days. Anyway my first OB appointment is on June 15th we should know more at that point.
I am thankful to have health care, but Tricare is a pain in the bum.
Thanks for your love and support.
