Quanity question

So I'm supposed to have my next appt with my sub doc on memorial day well I messaged Them And asked if that was still going to happen since it was Memorial Day and I didn't know if they were closed or if the pharmacy would be closed my. Doctor got back to me and said they're not letting him do appointments on Memorial Day so he could do it on the 26th or any day of that week I did it for the 26th but now I'm wondering will That mess up my quantity for my next month prescription Or should it be the same just because it's a couple of days early?
