Hello mam, thanks for trusting health care magic.
if the usg was normal after d&c then there is nothing to worry but definately you should visit your gynecologist for examination to see for amount and nature bleeding along with assessment of involution of uterus
In case you have further questions you can consult me on health care magic forum and i will be happy to help
Take care and wish you all the best.
Dr Manisha Jain.
