Pubic bone hurts?

Would this be a sign that baby turned head down at all?

When I walk or make any type of force it feels like someone punched me there.

Baby hasn't been head down at all since pregnancy except for ONCE and ever since she's been head up and feet down.

And this Friday at the ultrasound she was just like that as usual but why is my pubic bone hurting?

It's like the tip, where normally the "line" starts. So it's not the vagina.

Ps. I'm 36 weeks tomorrow, and I have a planned csection for some time in my 37th week.
