Shift from 2 % minoxidil to 5 % minoxidil, will this increase hair shedding?

Hello , I have been using minoxidil 2% for the past 4 months that's when my hairloss started . I still have hair loss and lost half of the density. All the blood work came back normal and I have no other health problems except the hair loss. My doctor suggested me to use rogaine 5 % once a day instead of rogain 2% twice a day.. but my fear is whether shifting from 2% concentration to 5 % will increase hair shedding.? Plz suggest
