Can you use Mifepristone and Misoprostol if you are still breastfeeding?
Keep breast feeding as normal. If you are nervous about it, there is a very low risk that Mifepristone or the Misoprostol metabolite could be excreted in breast milk during the first 5 hours, which could cause a mild stomach upset or diarrhoea in your baby.
