Hi, Welcome to Health care magic forum.
Most probably it is the product of conception,and bleeding . It is the normal out come after taking the pill.
I advise you to consult a gynecologist for diagnosis and treatment, to avoid the infection, after the miscarriage
Take more of green leafy vegetables, pulses, sprouts,and
protein rich foods to hasten the recovery.
Wishing for a quick and complete recovery. Thank you.
