Some info I found...
Because herbal teas contain small amounts of the herbs blended for flavor, it is probably safe to consume chamomile tea in moderation while you are pregnant. You should avoid using the stronger medicinal version of chamomile, including the concentrated chamomile oil. Chamomile is listed on the FDA list of GRAS (generally regarded as safe) ingredients and is widely recognized as a beneficial and safe herb. It is a good idea to check with your health care practitioner before you drink chamomile (or other herbal) teas. Most likely, they will agree that an occasional cup of hot chamomile tea while pregnant is fine.
