hi there, looks like a few bits of decidual tissue has not been evacuated completely and that is what is comiing out now. The pain is caused due to the spasm of the
uterus trying to get rid of these bits. Most probably all the bits are out and you may not experience any more pain, HOwever it would be wise to get a urine analysis done to rule out UTI and also an
ultrasound to confirm that the
uterine cavity is evacuated completely. You may take an antispasmodic for symptomatic relief. Take care.
