Hey kris

blue or black cohosh are herbs, that taken over a period of a few weeks, trigger uterine activity, which can lead to labor...I would certainly recommend seeing someone experienced in dealing with cohosh and pregnancy

a trip to a naturopath sounds great...sooner, rather than later, as the affect of alternative therapies can take at least a week to have some results

reflexology and acupuncture work well

good luck
