I may be facing the same decision soon. My body is only small and it has always been a concern that I may not have enough room through my pelvis for a baby to pass through. We spoke to our Obs on our first visit to him and he said we will have a closer look at that later on. Last week we had out third trimester growth scan and it looks like our baby boy is going to be big. He is already measuring 2 weeks ahead of himself. We have our appointment this Thursday with the Obs to discus what he thinks. I have made it clear to him that I am not interested in going through hours of labour only to have a c/s. He is aware of that and said we will see how we go but assured me he wont let it get that far. If he says to me that there is a chance that this will not go well vaginally and could end up being a c/s. I will have to decide if I give it a go or not risk it and book in an elective c/s. Honestly I would love to give birth vaginally but If I don't I am not going to think that I am less of a woman or that my body let me down. My body most certainly didn't let me down. We conceived and grew a healthy baby, I am happy to decide on a c/s if that is what is best to bring my little man into the world!
