I think I read somewhere that you have to be careful which kinds of tea you have when pregnant, or maybe I am mixing that up with something about essential oils in general, not sure where I read it.

Anyway, I have the following in the cupboard, would love to know which are OK and which may not be:

- blackberry
- spearmint & chamomile
- chamomile
- peppermint
- lemon

Are any of these going to be a problem if I drink some when pregnant (not more than a couple of cups a day, I don't go nuts on the stuff, usually).
