Hello,Emergency contraceptive pill
changes the hormonal
level in your body that is responsible for the menstrual cycle. Thus, it may cause changes in menstrual cycle in the month the pill is taken. Some women get periods in the very next week of taking the pill, as you have experienced. The pill changes the monthly cycle. Now you can expect your menstruation
around 7th December.
So as the pregnancy
test is negative, there is nothing to worry about. You can expect normal menstrual cycles from next month.
I hope this information helps you. Thank you for choosing HealthcareMagic. Take care.
