Caffeine during pregnancy

Sin • Wed, Dec 03 • 31 years old, mother of 2 beautiful girls, a handsome boy, and stepmom to a beautiful teenager. Married for 11 years

So I read on The Stir that caffeine intake can increase miscarriage chances by up to 14% and has been linked to childhood leukemia. Scary! I was drinking a cup of sweet tea daily but now I guess I'm going cold turkey! Has anyone else read this?
