Well, not the results I was hoping for but with the reasoning, I'm not too upset.
C-section is scheduled for June 13.
He took all the factors into consideration (period put me June 14, ultrasounds put me June 13, 15 or 20) so he is using a due date of June 15 to base it on.
He said they are finding babies born before 39 weeks are still showing signs of being a bit more premature than they would like, so they schedule between 39-40 weeks. He is gone June 6-10; said I could do June 8-10 if I wanted but would be a different doctor. I really like this one, so decided to go with his suggested date.
The unexpected news- my blood pressure is higher than he would like (was about 136 over 86 today). He is taking over care from my doctor, and said if it is high again next Tuesday, I will need to stop work, and we will reevaluate my csection date.
