Spitting up help!

Should I top my baby up after a spit up or not?

She just brought up what I'm convinced is all of her milk, there was so much and she did it around 4 times. She was being super fussy on the boob so I guess she needed to do that for a while and I didn't notice.

She's not showing any signs of hunger right now but I'm assuming she will soon because so much came back up?
