C-Sect or natural.

Hi mummies. I need some advice on this. My baby is 3.1kg at week 35+2 and my gynae told me my body frame can only take 3.4kg. He mention that I can still try for natural birth if I want but don’t try too hard. Should I still continue to try for natural delivery or just opt for c-sect? Or should I wait till another 1-2 weeks to decide.
