Please help! newborn baby projectile spit up?

my baby is 9 days old and is a big eater. She is now taking 4 ounces no problem. this morning i fed her and burped her every 2 ounces. right after I finished feeding I went to burp her and she spit up. I know spitting up is normal but this was like projectile vomit. Like it came out of her mouth with lots of force and was a large amount, looked like she was puking and looks like it was most of the bottle. she has done this three times since she was born and shes only 9 days old. I`m really worried, is this normal and what could be the cause of this? I don't think its the formula because she did this in the hospital once with different formula.
