I had a planned c section, i was fairly relaxed trough out the whole thing to be fair. They would have let me go natural up until my planned date but wouldn't let me go any further. I would have loved a natural birth, but it wasn't meant to be, my beautiful boy was delivered by c section at 38 weeks weighing 11lb 1oz!!! 



 glad he hung on for the scheduled date!  
In all seriousness, the hospital and diabetes center kept a very close eye on my, I had terrible dawn phenomena, sugars would go from 6 to 16 at 6am! And a planned c section was the best option, try not to freak yourself out about it, both you and your medical team will want baby out safely for u both, so what will be will be! Good luck x x x
