I would suggest you to consult a fertility specialist and get yourself and husband evaluated.
D and c used to be done in all cases previously, but now a days with good ultrasound
scan, hormonal profile and tube testing by HSG, and husband semen analysis
, we can diagnose any factor preventing you from conception.
So, depending on the test results, fertility specialist can guide you for further treatment plan.
If you need to do d and c, it should better be combined with laparoscopy
for having complete picture.
Hope this information is helpful.
