red raspberry leaf tea

37 weeks and two days. I heard the tea helps with uterine contractions. I've been drinking this and haven't felt nothing. not one. haven't had any contractions before drinking it either. just seems like he's content and don't wanna come out or is close to ready. altho I do have a induce date at 39 weeks. due to medical issues. but trying to prepare this uterus of mine. has anyone else drank this and had not anything happen?
