I think they say one cup a day is fine. I can't remember exactly because I just gave it up. I'm sure it's in any pregnancy book or a quick search online will tell you. Also, you can discuss with your doctor. You can try doing half caf to lower the amount of caffeine you are getting, but still enjoy some coffee.

Yes but limit yourself to 200mg of caffeine a day.

One cup of coffee is fine. My OB said decaf actually can have more caffeine so be cognizant of that. Keep your caffeine intake under 500mg a day :)
