Thanks for the query.
First of all i recommend you wife to confirm her pregnancy
by UPT kit.
Also for medical termination of pregnancy, diagnosis of intrauterine pregnancy is very important.
So i recommend your wife to get a transvaginal ultrasound
to know pregnancy state and weeks of gestation.
treatment depends on the weeks of pregnancy.
Please consult your Gynecologist for prescription as termination of pregnancy has to be done under specialized supervision.
Hope this helps,
