Had a medical abortion at 14 weeks. 3 weeks after , 2 hpt were negative. however, i feel "gassy" in my stomach. baby kicking? continuing pregnancy?

1st, why RU gassy?: Feeling gassy may reflect malabsorption of food (like gluten, lactose), intake of poorly digested food, or choosing foods known to promote gas (beans, fizzy drinks). Sometimes its more complicated--a stomach emptying too slowly, bacterial overgrowth syndrome, delayed intestinal function, partial obstruction from any cause, infection, rectum problems, pelvic pathology outside the gut, maybe stress.
