The morning after pill is not intended for regular use as a form of contraception. It is designed to be used in emergency situations and should not be used regularly as a replacement for other birth control methods.
Using the morning after pill on a regular basis can lead to side effects such as irregular periods, nausea, vomiting and headaches. Moreover, the long-term effects of consistent use of the morning after pill are not well known. It is always better to talk to your healthcare provider about a stable form of birth control to avoid unintended pregnancies.
