Thanks so much

Good evening mothers and doctors in the house, I really need your urgent advice.
I'm pregnant and I'm three weeks overdue, my due date is 9th of June, and I'm yet to go into labor, my doctor said I should wait from now till end of the month, the truth is I am scared as I don't know what to do, and scary part is scan also state that my baby is 3.5kg, which some people say it can make me go through c-section. Pls tell me, should I or should I not be scared. I'll appreciate any reply given to me. Thanks
