Hey Sammiejane

Im not sure about drinking it earlier...but I have heard that some people drink it purely for the taste..as a uterine tonic it is not going to have any negative effects on the pregnancy, but it may cause an irritable uterus (lots of BH) which can be uncomfortable, but are not any indication of preterm labor...remember that BH are great as they oxygenate the uterus and the baby
