I have been drinking red raspberry tea for about a week now. Since I hit 37 weeks, I drink about a glass every 2 days. I do notice I get braxton hicks contractions for a few hours after I've finished drinking it, so I would recommend not drinking it until you are term. From what my doctor has told me as well as the pharmasist has told me, it's completely healthy but should not be drank until you are term.
EDD with baby #1 for hubby and I September 21st, 2003! It's A BOY!
