Raspberry leaf tea

I bought some raspberry leaf tea in the beginning of my pregnancy because it was just labeled as “healthy pregnancy tea” but after doing research have learned that most women don’t even start drinking it until closer to their due date. But is it safe to be an overachiever and start drinking it earlier? I’m 30w so I’m beginning to do everything I can to prep my body for labor, but want to do it safely. I read that it can cause premature contractions and start early labor.

What is your ladies experience with it?

P.S. any other tips for getting the body ready for labor will be much appreciated 💕
