Stupid question ?

I<3Dolphins • I`m a 23 year old Military wife. My husband and I have been TTC #1 since November 13, 2013. ✨
Why is it bad to drink coffee while pregnant? I'm not pregnant yet but I read that it's bad. I also read that you will increase your chances of pregnancy if you drink little to no coffee. I LOVE coffee. I go to Starbucks almost every day. (I'm trying to stop).
