Herbal teas for pregnancy

I’m finding sooo much conflicting and confusing information on what herbs are safe for use in pregnancy. I love herbal tea and would like to make sure what I’m consuming is safe. Currently first trimester and I know some aren’t recommended for first trimester. It’s frustrating how much conflicting information is out there.

I don’t have a midwife yet, but will soon so I can ask them for more guidance. Unfortunately more OBGYNs don’t know much (or anything) about herbal remedies and I don’t have a trusted OBGYN right now.
