Failed d&c??

If your d&c; didn’t take, how did you know? Did your doctor do any tests or ultrasounds at a post-op appointment? Do you have any continued symptoms or cramping or old blood coming out? I can’t shake the feeling that something is wrong and I won’t be able to get pregnant again. When I called my OB’s office to say I still had spotting and went straight to having a period they said not to worry. I’ve had a period and still have occasional spotting of brown blood and sometimes get a cramping feeling like AF symptoms. Anyone have symptoms like this and know they’re okay?
