Hello mum's and mum's to be!

I am a FTM and I've put on 2 stone in 35 weeks making me 20 stone 😭 my midwife has told me baby is almost 6lbs and I'm carrying alot of fluid which she is happy about and baby is perfectly heathly.

I read on the NHS website that mum's with a high bmi are more likely to need an instrumental birth or a c section! I would love to have as natural birth as possible but if I'm likely to need help that way I thibk I would prefer a c section than go through that trauma. Has any other mums (20 stone plus) given birth naturally with no complications?
