sometimes herbal abortions dont work because:
--you arent clear whether or not you want to be pregnant.
--the herbs used are not strong enough to induce an abortion
--the herbs are not used for a long enough period of time
--the body grows a tolerance for the herbal dosage
--you are taking the herbs, but arent mentally/emotionally focused on the abortion
--nothing is certain. nothing is guaranteed. nothing is full-proof. in other words, it is a mystery.
