38 weeks and 5 days and my doctor won’t induce until 41 weeks

I’m pregnant with my 3rd, even though my first two babies were born weighing 10 pounds my OBGYN won’t induce until 41 weeks. I get the longer the baby stays the better, but why not just induce me at 40 weeks? I delivered my first two with no issues but what if this baby comes out bigger? I’m just so frustrated. I’m having extreme pelvic pain, I’m swollen all over, and i have like no energy. Does anyone else have an OBGYN that’s waiting til 41 weeks to induce?
