Ugh! That doctor sounds terrible! That is absolutely not the way you should be treated. SnS without consent is assault.
I know you're at the pointy end of things, but I urge you to think about seeking alternative care. I assume you're private? Would you consider hiring a private midwife instead and birthing in a public hospital, for instance? Or just go public. I had a much better experience at our local public - Swans - than I did with a private OB at Mercy.
You and your baby both deserve much, much better care than this.
