Don't know if it was the tea - but I was taking 5w pills from 5 weeks, but I could never remember to take them, got some tea and was drinking it in the last few weeks... was induced and had a 4 hour labour gas only, don't know if that was just luck or tea or genetics!
Have to say that I for some reason thought that "raspberry" leaf tea would taste like raspberry. My first mouthful had me in shock! It tastes like hay. Boiled hay.
But in that last few weeks it was good to have a focal point thinking that "perhaps" it might help with or induce labour!
