Can i do abortion with medaborn for 3 months pregnancy whiles am breast feeding 11months babe?

No: This medicine had limited distribution in the US, shouldn't be used by patients without close medical supervision, only to induce abortion through 9 weeks of pregnancy, again under strict medical supervision. You are already more than 9 weeks, almost 13 weeks pregnant, check with your doctor

Surgical option only: At 12+ weeks gestation, medical abortion has not proven to be successful. Therefore, surgical abortion is your option of choice which may affect your continuance on breast feeding.
