Teas that are safe to drink during the 1st trimester?

Hi all, so I am having major coffee withdrawal (went down to 1 cup of regular and 1 cup of decaf from my usual 3-4 cups a day 🙊), and it's been a rough habit to break. I love tea and was drinking herbal fruit tea as a replacement for my afternoon coffee, but I just read that certain types of teas are off limits. I realized the tea I was drinking has hibiscus leaf and from what I read that's not good to drink in the first trimester.  Does anyone have recommendations for caffeine free tea that's safe to drink? Thanks!
