Ceasereans or normal dilivery?

Im 5'5 and was 186 lbs when pregnancy started and I gained 22 lbs already and my 3rd trimester just started....

My doctor said that I have 90% chances that i'll have ceaserean because of these two factors.... Do I really have 10% chances of normal dilivery?

PLEASE DO TELL ME! I REALLY WANT TO HAVE NORMAL DILIVERY :(
