Energy drinks

Marie

I'm trying to conceive but I'm here at work dragging I'm so tired like fall asleep at my desk tired. I'm currently in my two week wait and aunt flow is supposed to come on the 13th would it hurt my baby if I drink an energy drink if I am pregnant? I plan to stop drinking energy drinks as soon as I find out I'm pregnant but I also don't want to hurt my chances of getting pregnant by drinking them or hurt my baby if I am already pregnant. Please help!
