Hello dear
I understand your concern
Vomiting and heart burn could be due to side effect of pill,
indigestion,
gastritis,
acid reflux, hormonal imblance.
I would suggest to consult your gynecologist for examination.
USG should be done to confirm completeness process of abortion.
You can take following advises for vomiting and heart burn:
Tablet
pantoprazole and domperidone
Syrup mucaine
Take small frequent diet rather than large meal
Avoid spicy/fatty/oily food,
Take food like banana, applesauce, rice, toast and yogurt.
Drink plenty of water, maintain proper pelvic hygiene, take proper rest.
Hope this may help you
Contact further if follow up needed
Best regards
Dr. Sagar
