thank you for your query.
The I pill
is an emergency hormonal contraceptive
It has not shown to have any impact on future pregnancies.
The i pill has a side effect of causing your menstrual cycles to be irregular and unpredictable, even though this is also mostly a temporary effect.
Very rarely, irregular cycles can lead to irregular ovulation and difficulty in conceiving.
Apart from that, it has no bearing on your future childrens' health.
Please do not worry.
Always have protected sex in the future, till you plan a pregnancy
