Thanks for the query.
According to your ultrasound
- Uterus came back to normal size. No retained products.
-Sometimes fluid collection in pouch of Douglas seen for few weeks after abortion.
But as you are having pain abdomen better to rule out pelvic infection
the ovulated follicles forms corpus luteum
of pregnancy and they will remain for weeks.
Your corpus luteal cysts probably representing them.
These will usually regress soon without the need of medicines.
So consult gynecologist once, if she diagnoses presence of pelvic infection, go for antibiotics with her advice.
