This might help on your questions above. However, it is highly advise you get consultation from your gynae/doctor pertaining this. End day, decision will be in your hand. Not everyone can go through VBAC esp if baby is too big, previous scar seems to be painful or has opening that can rupture. One of the celebrity, Nadiah M Din she did a successful VBAC before, perhaps you can also ask her experience too.
