Hi,
Thanks for the query.

You should not take tablets for abortion without consulting the doctor.
So you once consult gynecologist, get examined and go for one ultrasound.
Ultrasound is needed to confirm the intrauterine pregnancy, to estimate the gestational age and to exclude ectopic pregnancy.
After that with your doctor's advice you can go for tablets.
If you take the tablets without getting examined that can lead to complications.
So better consult doctor once.
Hope I have answered your query. I will be available to answer your follow up queries. If you are satisfied with all my answer, please rate the answer after closing the discussion.
Take care.
