How do i cause a miscarriage at 18weeks?

Baby fetus growing: That's a big baby fetus already, maybe 5-6 inches in size. Don't want to destroy baby fetuses that size unless there is an enormously important reason such as a big birth defect, a case of rape, or the mother's health is endangered by pregnancy. Women in the US are free to ask their doctors about surgical abortions. One's Ob-Gyn doctor can help with the decision, as this is a major life decision.
