If you're only 8 weeks now I wouldn't sweat it (yet). That's quite a ways away and it's not worth worrying about at this point. 37 weeks is considered full term anyway. When I was pregnant that topic wasn't even brought up until two weeks before my due date. My due date was Sept. 17 and I was induced on the night of the 12th and had my daughter at 2pm on the 13th. I was already 2cm dilated. Who knows, you could have the baby on your own at or before the 38 week mark. I understand that the doctors are concerned about diabtes-related risks/complications in the pregnancy going beyond the due date and they want to reduce the chance of that happening.
