Thanks for the query.
You should not use tablets for abortion
without consulting the doctor.
So consult gynecologist once, get examined and go for ultrasound
Ultrasound is needed to confirm the intrauterine pregnancy
, to estimate the gestational age
and to rule out ectopic pregnancy.
So after doing ultrasound only, the doctor can advise you the mode of abortion.
Up to 7 to 8 weeks of intrauterine pregnancy, medical termination with tablets is possible.
Beyond that gestational age, tablets may not complete the abortion.
All the tablets you mentioned can be used orally.
But you have to use only after consulting your doctor.
