Passion fruit tea from Starbucks bad while pregnant?!?!?!

So after 2 or 3 weeks of drinking a trenta Passion fruit tea daily I am now reading that Passion fruit has hibiscus in it in that is very bad for you. I was completely unaware of this information and I thought it was safe to drink because it was caffeine free I am totally freaking out and the only thing I can do is wait until my doctor responds has anybody else drink this tea and turned out fine while pregnant?
