Pop & pregnancy?!

In the morning, I love a little pop in the morning. I have a 2 year old so I am up in the middle of the night, I am up and ready to go at 5:30, work all day, and I also have a 10 year old I get ready so I need a little pick me up. I don’t like coffee so a little 24oz pop just gets me moving once I get to work. After my pop I drink tons of water and the crystal light juice which is basically water. Is that one pop bad for pregnancy, oh I forgot I am just about 8 weeks pregnant and I am so exhausted!
