Dear lybrate-user! your gf is in for trouble if she keeps on popping ipills at will! Ipills are specifcally meant to be used in cases of unplanned and unprotected sexual contact once in three to four months at max. They are specifically not to be used routinely The present delay if ipill
was ingested affer 72 hours of exposure might be due to ipill itself. For more details do consult online or visit your doctor.
