Raspberry tea—when to start?

Co

Hi ladies, I’m 30+3 and have bought some raspberry leaf tea. I was going to start drinking a cup a day (when I remember to) now, then increase to two cups when I’m around 34-36 weeks. Does this sound okay? I know it’s for toning the uterus, not inducing labor, and I’m definitely not trying to have this baby early. Just looking for experiences and recommendations!
