Welcome to Heealthcaremagic.
Taking Unwanted 72 is the only choice available now other than getting a copper T inserted for emergency contraception
Unwanted 72 contains high dose of progesterone
which is the same but low dose in rgestrone.
Hence taking unwanted 72 will surely affect the periods causing irregularity in them.Do consult your gynaecologist for the same.
Wish you good health.
