hello,, i had a medical abortion at 6 wks of pregnancy..after that i bled for almost 2 wks..after 18 days of taking the pill i had an ultra sound done which shows.. endometrial thickening due to ?retained products ??blood clots...now after 5 days of the u.s.g. i am not bleeding at all..do i need a d&c? if i do not do a D&C,,can it cause problems later on?
