Thanks for your query.
Firstly, DO NOT TAKE any medications without consulting a gynecologist.
Have the pregnancy
confirmed by a gynecologist, then have proper dating of the pregnancy in weeks.
After that, take the pills as per the prescription provided.
Then have a follow up visit to confirm that the procedure was complete.
Do not skip ANY STEP - you run risks such as infection, severe uncontrolled bleeding, incomplete abortion
All the best.
