30w4d RaspberryLeaf Tea?

I’m 30w4d with my second baby, do you guys think it’s too early to start RaspberryLeaf Tea?

I didn’t have any complications my first pregnancy & no crazy fast labor (google says to avoid if I had premature labor before) I just don’t know if I should wait a few more weeks to start drinking it or not or now is fine? When did everyone else start?
