Due date off won’t induce

I’ve had a feeling since the beginning of my pregnancy that my due date is wrong. I know for a fact when my lmp when I ovulated and when I got a positive test. That would put me edd 5/12

Well according to my ultrasound at 10 weeks they are saying I’m due 5/20.

I don’t feel that way at all and my whole pregnancy baby has been measuring 2+ weeks ahead. Closer to what I feel is my due date. Now I’m getting to the end of my pregnancy I’m worried because where I go they don’t induce until week 41. If that’s the case I feel like it will be dangerous for me to go that long!!!! I want to try to start to promote labor myself by 38 weeks. Any tips or advice?
