So I had a scan at 20 weeks, which showed he had an abdominal circumference over the 97th centile. They said this will likely reduce as its still very early.
I then has a growth scan a few days back at 31 weeks and they said he's on the higher centiles for most measurements, including his weight which is 5 pounds. But his abdominal circumference again is over the 97th centile 
They have booked a gestational diabetes test next Friday, then a scan at 35 weeks to review his size, abdominal circumference and where to go from there.
If I did have gestational diabetes would they induce early or do an earlier C section? If I don't have gestational diabetes, but his measurements are still large (especially on his tummy), will that result in the same possibilities? My midwife said they can induce early sometimes but I feel no one has properly informed me what to expect 
I'm just very worried about giving birth to him if he's large in case of complications such as shoulder dystocia. I just feel a bit in limbo at the moment as I'm not sure what possible options there are!
Any advice, experience?
Anxious new mummy!
