Can I have two castings of minor illusion active at the same time?

I had made a new half-elf sorcerer who will soon be a rogue multi-class. His spells are based off of what a rogue would choose them to be, such as fog cloud, mage hand, and minor illusion. In addition, I chose prestidigitation in the hopes of combining with minor illusion, using one for sound and one for an image.

Yet it was never clear to me if I could just use minor illusion twice, as it is a cantrip. This will free up a cantrip spot for a more offensive spell, seeing as all of my other spells are more ability than offense. We are playing D&D 5E.
