How much is too much spit up?

Di

I'm wondering if the amount of spit up my baby has after breast feeding is normal or not. Hoping she doesn't have acid reflux! The last 3 days, she's spit up a couple times per feeding. About 50% of the time, she fussed afterwards. I try to keep her elevated and not move her too much after she eats. The spit up isn't a crazy amount most times. Any insight?
