LR keep away from 'pure' rasberry tea until your last trimester hun as it's used for toning the uterus and you don't really want too much of that happening till you're ready to get the baby out iykwim?!
I'd even be careful in the first tri with rasberry blend teas if you tihnk you might be a sensitive type.
Chamomile and ginger will be lovely, and if you get ms then mint might help(or make it worse like it did for me lol). St Johns Wort is the only other one I can think os to stay away from your entire pg.
Oh, if you can find it- usually at an organics store- nettle tea is excellent for throughout pregnancy 
Edited to add- I think coffee is fine in small quantities. I drank a cup a day throughout both pregnancies, it's when you're more like a 6 cup a day kind of gal that you might wanna cut back lol
you might find in a few weeks you'll go right off it anyway!
