Dr wants to deliver baby at 38 weeks...

Tanika
I'm a FTM and at my Dr's appointment today my dr informed me that my C-section would be scheduled for 38 weeks.  I've previously had a myomectomy and was told at the time of surgery that I'd have to have a c-section if and when I became pregnant, but 2 weeks early? Is this normal?  My actual due date is 12/28 but c-section is scheduled for 12/14. 
Also I've had no issues with my pregnancy and baby and I are both healthy. 
Just trying to see what others have experienced when it pertains to c-sections.
