thanks for the query
is a combined oc pill
the rule is One tablet is taken every day for 21 days and you then have a seven day break from pill-taking.
since you are not taking the pill prior to the sexual relationship there is a chance of getting pregnant.
emergency pills are generally preferred after unprotected sex
so its better to go for a pregnancy
test. you can do it in ur home by kits available in market
if the test comes positive consult your gynecologist
