I drank a 12oz mocha from an espresso shop (storyville coffee) and completely spaced on asking for decaf :( and forgot about it until after I drank it! I haven't had any caffeine since I got pregnant. Is this gonna hurt the baby? I am almost 15wks and the 12oz says it has 152mcg of caffeine which I know is under the 200mcgs allowed a day. My son has a fast heartbeat anyways (170s) and I am worried it is gonna hurt him. I'm obviously a first time mom :(
