I will advise u stick to ur doctor's advise. Forget abt d scan. I av someone who scan told her baby is 2.7kg so she was happy she could attempt labour, 3 days later, she falls into labour, had prolonged labour, was taken to d theatre and she lost d child, d child weighed almost 4kg. Besides, a big baby isnt d only reason for CS. A healthy mum and baby is all dat matters. Im sure ur doc and ur midwives know whats best for u.
