Red raspberry leaf tea: how far along when you started drinking it?

Cassandra

Okay so I'm considering trying it this pregnancy but I've read mixed articles on when to start. When I asked my OB about it at my last appt he didn't give me a gestational time frame just said I could drink it if I wanted and that he has no 3vidence it actually works. I've read 32 weeks I've read 34 weeks I've seen 36 weeks. So I'm not sure when. Help please.
