Hi thanks for your question.
I am sorry to say there is no home remmidies for emergency contraception
If attending next day duty is an issue. Post pill bleeding is usually as heavy as your normal periods and you can attend your next day dutiy as usuall ,but sometime heavy bleeding do occur.
As for as issue of abortion
is concerned,emergency contraception is not abortion ,Abortion is once the fertalized ovum is implanted in uterus
and then geting it removed.
Emergency contraception you don't allow the ovum to get implanted in uterus.
Hope this answers your question.
