So I let my mom take my 2018 Q50 Red Sport to go get grocery’s today because her car is getting fixed from a car accident & she’s used to always pumping regular gas in her car so she forgot to put premium in mine & put a half tank of regular gas ... Should I be worried ??????

Just be gentle with the car until you burn through the tank. Worst case, it's probably at an octane between the two...that is all gas stations do to create mid-grade, is blend the lowest and premium octanes.
If everything is functioning correctly, the ECU should retard timing once it detects knock, etc. But try to avoid getting to that point to be on safe side as there is always a small delay (ie has to occur for computer to 'know').

Sounds like she put 'regular' in though, which is typically 87 (or lower, say high elevation where 85 exists)...but, if premium is indeed 93 where the OP is and it's a perfect 50% mix, then that would be ~90 octane and be close to 'premium' in other states, such as here in commiefornia.

That and just keep it easy on the load until you burn through the tank. The ECU should compensate by retarding timing and such, but don't rely on it. Further, keep in mind higher elevation can get by with lower octane, if you drive in such an area...fwiw.
BTW - noticed this is a 2014 in question...does the 3.7 "require" premium? I know the wife's maxima (3.5 L) "recommends" 91 premium but at same time indicates you are able to run lower grade 87 min., at the expense of performance vs. 'damage'.
