Chody I would say yes about the CS for a number of reasons, mainly a smaller bub has less reserves to cope with labour and would get into distress more easily,is often not head first yet and also to induce a labour earlier than term is often very difficult as your body isn't ready and would most of the time end up a failed induction/ CS.
Often a slow growing baby has a placental issue, so the stress of labour on a not-quite-100% placenta would be too much.

Anyway, good luck and I hope this isn't an issue, but its good to be informed of the possible outcomes, so you don't get shocked if the Dr suggests CS!

You might at least get a few more weeks with regular scans.
