D&C for retained tissue 9 weeks after MC

Cherie • 👼🏻8/21/19 🌈 👶🏼 baby girl due 3/18/20

I wanted to avoid a D&C originally because of my fear of Asherman’s syndrome. Anyways my D&C is scheduled for tomorrow and it is only to remove retained tissue that has been there now for 19 weeks (10 during pregnancy 9 post miscarriage). Has anyone had a D&C for a similar reason and if so did you have any complications/ or was everything fine? I am absolutely terrified of not being able to have kids because of this :(.
