Well if you are very sure of your dates , then take 1 mifepristone 200 tablet orally first followed by 4 tablets of misoprostol
(zitotec 200) orally, after 48 to 72 hrs.But before that i would like you to consult a gynecologist and do a pelvic ultrasound
if required to know the exact age of your pregnancy
. Sometimes if this fails and culminates in incomplete abortion
,you can have torrential bleeding, so it is prudent to consult a gynecologist earlier.
Regarding the side effects ,you can a have gastric upset, nausea,vomiting
or loose motions etc like symptoms.Nothing to worry and you can take additional symptomatic medications if required.
Good luck bye
