Chance of baby coming early?

So this is my third pregnancy, and will be my third c section. I’m due August 8th but I’m 90% sure the doctor has scheduled my due date later than what it should be. I’m 14 weeks tomorrow.

My last two children were both born early, my first at 34+2 weeks via emergency c section, and my second was born 36+3 via c section but I went into labor so she felt it safe to deliver. With that being said, what are the chances that this baby will be born earlier than the due date? Can you schedule an earlier date for your c section? Please help!
