I am so sorry for your loss. I've had 5 MC and required 3 D&Cs. Since then, I have had a successful pregnancy which resulted in DD and am currently pregnant with twins from a FET.
I did have a hysteroscopy before my first successful cycle and an SHG before my FET.
I found the D&C to be easier to handle both physically and emotionally. But others will completely disagree.
Please be gentle with yourself.
