Tea..?

I'm nervous because I bought some herbal tea the other day to help with a sore throat and then just noticed today that it says don't drink while pregnant/breastfeeding. Now I am stressing and thinking Why didn't it cross my mind to read it before drinking. I saw caffeine free and thought okay now I feel really bad about not even thinking to check. I think It says not too because I noticed it has licorice root in it (which I googled and that always seems so turn out bad). Called my doctors office the nurse said since I've already had it there is not really anything to do besides stop drinking it. Has anyone else done this or drank tea not recommend and everything turned out ok?? This is my first pregnancy so I'm kind of freaking out 😥
