Help on FAFSA

I submitted my FAFSA on the day it opened for year 2017-2018, but later on, i had to add and delete some colleges forcing me to submit my fafsa again. I know that FAFSA is on a first come-first serve basis so I am really worried that the corrections i made will effect the date of my original submission…
SO in conclusion, my question is; will the original day i submitted my FAFSA be affected due to my edit or is my spot still saved because i have aleady submitted my fafsa earlier?

sorry, im not sure if my question makes sense but PLEASE give me some answers as i am EXTREMELY concerned…

You either qualify for a Pell grant or you don’t. As long as the FAFSA processed before you deleted schools to add others you should be fine. Aid at some colleges can run out later in the year, but students who run into that are those who file in the spring. A few days in Oct. aren’t going to make any difference.
