My doctor told me it's okay to have a cup daily

You can have something like 200mg of caffeine. I usually have a pop and a tea or lots of chocolate whatever. As long as you're not overdoing it. Like having two energy drinks or something crazy!

One cup is the daily limit you have for caffeine. I drank one cup some days once I was in my 2nd trimester

I drank coffee with my pregnancy. I think it's all on how you feel after you drink it.
