Thanks for the query.
I understand your concern.
The possibility of pregnancy is less as you have taken emergency contraceptive pill within four hours of intercourse.
Better to avoid emergency pills during breast feeding as some of these hormones can pass to baby.
One pill may not lead to much problem, but repeated use is not advisable.
