Concerned about artificial dyes!

It’s been a week that I’ve been drinking Gatorade to help increase my amniotic fluid. Dr recommended to drink water and 2 gatorades a day diluted with water. He wants me to keep taking them until my due date. However I’m concerned about the artificial dyes in the Gatorade that I’ve been consuming dyes yellow #5 & 6. I’m worried that consuming too much dye to be harmful to my baby..
