thanks for the query.
Pill 72 is intended to prevent pregnancy
after known or suspected contraceptive
failure or unprotected intercourse
Pill-72 Emergency Contraception
reduces the average risk of pregnancy among users from about 8 percent to about 1 percent. After a single act of unprotected sex, correct use of Emergency Contraception reduces the risk of pregnancy by 89 percent.
One tablet of Pill 72 should be taken orally within 72 hours after unprotected intercourse. The second tablet should be taken 12 hours after the first dose. Efficacy is better if Pill 72 is taken as directed as soon as possible after unprotected intercourse.
Wait for your next periods.
If you miss your periods get a UPT done and contact your gynaecologist.
hope this helps,
