welcome to HCM,
taking emergency contraceptive
pills so frequently is very harmful,
they have a lot of side effects,there may be incomplete abortion
, you may have irregular cycles, there may be problems in further conception.
taking 4 pills at the interval of 12 hrs is the regimen followed because of the pharmacokinetic and pharmacodynamic of the drug , with this interval this drug gives the best result. if the interval between the two doses is increased the efficacy of the result decreases.
