Red raspberry leaf tea. I'll drink it....

Every time I drink this, it makes me really aware of my uterus. It's weird. But I want to know what you all will do, since there are so many different recommendations about it. I heard it can make birth so much smoother! And I don't really buy it when studies say you shouldn't do something because it hasn't been double blind control tested (which is usually unethical in pregnancy safety tests anyway). Still, some midwives say to hold off until the last month. What have you decided?
