Do you think my doctor wants me to get my bloodwork done exactly 3 days before my appointment?

I had an appointment with my doctor 3 months ago. I remember her telling me to get my bloodwork done 3 days before my appointment. I called the receptionist twice, and she said to try not to get the bloodwork done less than 3 days before the appointment. Im guessing that it doesn't need to be exactly 3 days before the appointment, so long as I do it before 3 days before the appointment? I dont want to call, and ask again, because i feel like and idiot.
