Throwing up cleaning liquid!

Im a FTM and my daughter had just thrown up twice clear liquid with a bit of milk curds. This wasn’t spit up, this was definitely throw up. Should I be worried? Does anyone know what this could be? I’m making an appointment tomorrow because she’s sick but I thought I’d ask anyways!
