hello dear.
understand your concern.
first of all you should confirm the
pregnancy by blood
HCG test because its more reliable method.then you should do USG for confirmation of intrauterine pregnancy,because drug only applicable for intrauterine pregnancy.
you can abort fetus by medicine up to 9 weeks of pregnancy.
you should do it under supervision of doctor,its more safe.
you can take pregout kit,which contain 5 tablets.
take 1 tablet of mifepristone 600 mg orally,after 36-48 hours of it take another 4 tablets of
misoprostol 200 mcg placed in vagina one by one.
at that period take proper rest,food,maintain hygine,take tab .meftalsaps for pain.
hope this will guide you.
best regards.
