There is a tea (mothers milk?) that I *believe* is safe during pregnancy. You can contact you local LLL and they may be able to help. In the pregnancy section I think there may be a thread about breast feeding during pregnancy.
I lift my eyes unto the hills, Where does my help come from? My help comes from the Lord, The Maker of Heaven and Earth. And I'll praise You in this storm and I will lift my hands, For You are who You are no matter where I am, And every tear I've cried You hold in Your hand, You never left my side and though my heart is torn, I will praise You in this storm
